Not every Interseller alternative solves the same problem. Switching platforms isn't simply a matter of finding more profiles or buying a contact database. A recruiter has to compare sourcing coverage, the quality and verification of emails and phone numbers, outreach automation, ATS integrations, cost per credit or per user, and GDPR controls.
The right choice also depends on the kind of operation you run. An independent headhunter needs speed and control over spend. An agency or staffing firm may prioritise volume, enrichment and repeatable cadences. An in-house Talent Acquisition team usually needs its ATS integrated and its pipeline traceable, while an RPO is looking to standardise processes across several clients.
The list below groups the tools by the problem they solve: AI sourcing, contact enrichment, multichannel outreach, talent CRM and follow-up automation. It includes public pricing or quote-based models wherever that information is available, along with operational limits and what each one means for day-to-day work.
In Spain, these decisions carry an extra dimension. The rules governing electronic marketing and data protection in Spain demand attention to the legal basis, the origin of the data and the objection mechanisms available. That is why HeyTalent fits as an intelligent sourcing layer that can complement an ATS such as Teamtailor, Viterbit or Workable, rather than replacing the system where applications are managed.
1. HeyTalent
HeyTalent is most useful when the bottleneck sits before the first message — in finding, filtering and prioritising candidates. The platform brings together public profile extraction, enrichment with emails and phone numbers, customisable AI filters and automated outreach. For the recruiter, that flow cuts down the work currently spread across LinkedIn, spreadsheets, data vendors and cadence tools.
Search supports job titles, keywords, location, experience and company size. Its AI variables let you build your own criteria to assess, for example, an advanced or bilingual level of English, or an age estimate based on academic and professional history. The operational advantage lies in turning requirements that are hard to structure into filters you can apply to a list of profiles.
What it means in practice: if the team spends too long reviewing results, configurable filters may be worth more than yet another tool focused purely on sending messages.
What the team gets
The workflow covers extraction, filtering, enrichment and contact from a single interface. Its euro-denominated plans include unlimited users and variables, unlimited CSV exports and control over credits and costs. The range runs from freelancers working with up to 2,000 candidates a month to teams with capacity for up to 14,000 candidates a month, according to the published product information.
HeyTalent also publishes internal figures on an improvement of up to 60% in speed during the first month, a reply rate of 2.5x and savings of up to 5x compared with LinkedIn Recruiter. Those numbers need validating yourself, because they are not an independent comparison. An agency should test them against its own profiles, markets and messaging before folding them into a productivity forecast.
The platform can complement HeyTalent's free ATS and other systems on the market. The ATS keeps the vacancies, the pipeline and the management of applications, while the sourcing layer prepares profiles before they are logged in the main system. That separation avoids asking the ATS to perform discovery functions it doesn't always cover.
Limits worth checking
HeyTalent doesn't replace every native LinkedIn function. Some connection-with-note campaigns may require a LinkedIn Premium Business account. Coverage and accuracy also depend on the public data available and the enrichment applied, with possible differences by country, sector and profile type.
GDPR compliance has to be reviewed campaign by campaign. The platform states that it processes public data under legitimate interest and offers instant opt-out, but the recruiter still has to document the legal basis, handle objections and control how the information is used afterwards.
Best fit: headhunters, agencies, Talent Acquisition teams and RPO providers that need to speed up sourcing and reduce their exclusive reliance on LinkedIn licences.

2. SourceWhale
SourceWhale sits closer to a talent engagement and sales engagement platform for recruiters than to a simple contact finder. It centralises sequences across email, calls, SMS, WhatsApp and LinkedIn, with a Chrome extension that lets you work from LinkedIn profiles, an ATS or a CRM.
For an agency, the advantage isn't only sending more messages. It is that the recruiter can keep notes, calls, enriched data and next steps inside the same flow. That cuts the constant switching between apps, especially when a campaign combines an initial touch, a follow-up call and a message on another channel.
The extension also surfaces contextual information — news, funding rounds, open roles — that can be used to personalise a message to a company or a passive candidate. The AI modules help with notes, call summaries and personalisation, though the final quality will depend on human review and how the team configures it.
When it makes sense
SourceWhale suits agencies that already have a defined outreach operation and need to coordinate several channels. A consultant who just wants to find emails could end up paying for breadth they never use. A team running urgent searches that needs every interaction logged, on the other hand, stands to gain from the centralisation.
The platform was designed specifically for recruiting rather than adapted from a generalist sales tool. That orientation can make adoption easier for recruiters who have to handle candidates, clients and conversations within the same process.
The cost of customisation
Pricing is bespoke. There is no simple public rate to compare per user or per credit, so the evaluation has to cover modules, contact volume, available channels, integrations and support. For a small agency, the lack of transparency makes it hard to work out the real cost before a demo.
Pros: multichannel sequences, Chrome extension, enrichment, data refresh and AI modules built around the recruiter's work.
Cons: quote-based pricing and a potentially higher cost than generic sales tools.

3. Gem
Gem is better at solving nurturing and long-term relationship management than a one-off search. Its proposition combines a Talent CRM, AI sourcing, an extension for LinkedIn and Recruiter, email and SMS sequences, analytics and send-on-behalf-of automations.
The operational shift is significant. Instead of treating every candidate as an isolated contact, the team can maintain a talent-community view, keep a record of past campaigns and review which messages generate engagement. That is useful for technical or specialised profiles that are rarely available at the exact moment a role opens.
The extension captures profiles from LinkedIn and other pages, while the AI modules help with search and template generation. The recruiter still has to validate the fit, but can spend less time building every campaign from scratch.
Talent CRM versus ATS
Gem can integrate with an ATS to add a relationship and campaign layer. It shouldn't be assessed as a replacement for a candidate management system. The ATS organises vacancies, stages and processes; Gem focuses on maintaining conversations, audiences and outreach metrics.
The platform takes a CRM view of the talent pipeline, with multi-stage sequences and scheduled sends. That structure favours in-house teams with recurring hiring and agencies that want to revive candidates from earlier processes, provided the integration keeps records coherent and consent controls in place.
Pricing is quote-based, so you have to request a proposal. The real scope will depend on users, automations, integrations and the modules contracted.
Best fit: Talent Acquisition teams and agencies that need sustained nurturing, not just an immediate outreach campaign.
Limit: as a basic ATS or CRM it can fall short against specialised systems, so its value rises when it is connected to the existing ATS.

4. hireEZ, formerly Hiretual
hireEZ combines AI-based sourcing, verified contact data, outreach and an integrated CRM. Its position appeals to organisations looking to consolidate several pieces of the stack, especially when security, governance and integrations matter as much as search speed.
The platform offers verified emails and phone numbers, outreach automation and analytics. It also carries ATS and HRIS integrations, connecting the identification and contact phase with the selection process that follows. For an in-house team, that link can eliminate manual exports and duplicates.
Compliance as a buying criterion
hireEZ documents certifications and compliance frameworks including SOC 2, ISO 27001, ISO 27701, GDPR and CCPA. That can make vendor assessment easier for companies with formal security requirements, although a certification doesn't remove the recruiter's obligation to define a legal basis, limit use and respond to objection requests.
In Spain, traceability matters especially when enrichment and outreach are combined. The guide to GDPR-compliant sourcing helps you frame the right questions about data origin, legitimate interest, retention and opt-out before a campaign goes live.
Cost and fit
Pricing is customised and does not appear as a public rate on the website. You have to request a quote detailing modules, volume, users, integrations and support. A comparison with Interseller will only hold up if you calculate which tools it genuinely replaces and which will still be necessary.
Pros: a solid focus on compliance and security, contact data, CRM, outreach and enterprise integrations.
Cons: non-public pricing and commercial scope that depends on modules and volume.
5. Apollo.io
Apollo.io was born for sales intelligence and engagement, but it can be useful for recruiters who prioritise finding emails and phone numbers alongside outreach cadences. It includes a broad database, data credits, email and call sequences, plus an extension for working from LinkedIn.
Its main advantage is the ratio between functional breadth and entry price. Public plans let small teams understand the initial cost before committing, which isn't the case with quote-based alternatives. There is also a large community and training material, which can speed up getting started.
Adapting it to recruiting
Apollo.io wasn't originally built around vacancies, candidates and selection processes. The recruiter will have to adapt fields, stages and messaging to their own methodology. For an agency that needs contact data and a simple sequence it may be enough; for a team that requires detailed candidate history, specific compliance and close coordination with an ATS, it can fall short.
Data quality outside the United States has to be tested in your target market. Don't assume email and phone coverage will be uniform for Spanish profiles, technical niches or candidates who don't publish professional contact details.
Pros: public plans, broad functionality, a learning community and a good entry point for small teams.
Cons: a sales orientation, potentially less consistent data outside the United States and less specialised recruiting workflows.
6. Lemlist
Lemlist makes sense when the bottleneck is in running personalised emails and protecting deliverability. Its core is email sequences, dynamic templates and warm-up tools. For recruiters who already have a source of candidates, it can become the contact layer.
The recruiter can create message variations and automate follow-ups without building every email by hand. That helps with passive-candidate campaigns, but personalisation has to start from correct data and sensible segmentation. Automating an irrelevant message only means sending it faster.
What it doesn't cover on its own
Lemlist is less oriented towards deep multichannel automation. If the strategy requires combining email with calls, WhatsApp and LinkedIn actions in a single cadence, you will probably have to add other tools or accept manual work.
Its public plans and credit information make cost estimation easier, though the final calculation has to include the data source, verification and any ATS integration. The tool doesn't automatically resolve the legal side of data processing. The team has to verify the legal basis, the context of the outreach and the objection mechanism before sending anything.
Pros: ease of use, personalisation and a focus on deliverability.
Cons: less depth for multichannel recruiting and a dependence on another tool for sourcing and enrichment.
7. Reply.io
Reply.io brings email, LinkedIn, SMS and calls together in multichannel cadences. Its operational difference lies in including LinkedIn actions — messages, voice notes and profile visits — inside a broader sequence.
For a recruiter, that means designing a contact path that doesn't depend on remembering each task in a spreadsheet. A campaign can alternate an email, a LinkedIn interaction and a call, with follow-up conditions defined in the platform. The team should always check that the automation respects the channel's rules and the outreach strategy.
Multichannel automation works best when every touch adds context. Repeating the same message over email and LinkedIn isn't a cadence, it's duplication.
Value and caveats
Reply.io offers broad coverage in a single plan, which is useful for agencies working across different profiles and clients. It also provides resources and guides on engagement that can help standardise internal training.
The product experience deserves a trial before you migrate. Recent interface problems and bugs have been flagged, along with complaints about price increases in certain cases. These shouldn't be treated as universal facts, but they are reason enough to run a complete campaign, test support and ask in writing what the commercial proposal includes.
For a deeper look at the limits of automating LinkedIn actions, see this guide to automating LinkedIn messages.
Best fit: teams that want to combine several channels from a single sequence.
Limit: possible stability issues and commercial terms worth validating during the trial.
8. Lusha
Lusha is primarily a B2B database of emails and phone numbers, though its Engage module adds email sequences and follow-up. For recruiters and agencies, it works as an enrichment source that can feed the ATS, the CRM or an outreach platform.
The extension surfaces contact information from within the workflow, and its integrations connect to both sales and recruitment systems. Tiered plans, from Free up to enterprise options, make it easy to start with credits and scale usage with volume.
Working out what a credit really costs
A credit doesn't necessarily equal a candidate contacted. The team has to measure how many profiles get enriched, how much of that data is valid, how many contacts meet the project's criteria and how many conversations they generate. If the agency pays for data it then can't use for lack of a legal basis or because of low relevance, the operational cost rises even when the headline price looks competitive.
The guide to obtaining contact data for recruiters is useful for reviewing the difference between having an email and having a defensible process for using it.
Users and comparison sites have noted a good quality-to-price ratio, but there are also complaints about price increases and changes to terms. Before signing, review plan limits, credit expiry, exports, integrations and usage rules.
Pros: a balance of database, enrichment, Engage and integrations.
Cons: commercial changes reported by users, and limitations that depend on the plan and the volume.

9. ContactOut
ContactOut focuses on one very specific task: revealing personal emails and phone numbers from LinkedIn profiles through a Chrome extension. It works with LinkedIn Standard, Sales Navigator and Recruiter, and also supports enriching batches of URLs.
Its value appears once the recruiter already knows which profiles they want to contact. The extension shortens the time between identifying a person and getting a channel other than LinkedIn messaging. It also offers simple email campaigns, though without the breadth of a specialised multichannel platform.
A fast source, not a complete system
ContactOut can complement LinkedIn and an ATS, but it doesn't replace a sourcing, prioritisation or relationship-management strategy. User-perceived accuracy can be good in certain tests, but results vary by niche, by country and by how much public information is available.
Pricing is unclear and geared towards a commercial quote. That lack of visibility forces you to request detail on credits, bulk enrichment, users, exports and campaigns. An agency should work out the cost per valid contact, not just the cost of access to the extension.
Pros: speed in pulling data from LinkedIn and batch enrichment.
Cons: opaque pricing, basic campaign features and coverage that varies by specialism.
10. Snov.io
Snov.io is an email-first alternative for teams that need to find and verify addresses, search by domain and launch campaigns. It includes a LinkedIn extension, open and click tracking, a lightweight CRM and public plans based on credits and users.
For a small agency, the clarity of the model makes it easy to start with a trial and calculate the cost of bulk extraction. It can also be combined with an ATS or CRM through integrations, though the recruiter has to check which fields sync and how duplicates are avoided.
Where it fits best
Snov.io works well when the project depends on verified emails and relatively simple campaigns. LinkedIn automation is limited for a pure recruiting flow, and it isn't as geared towards complex multichannel cadences as SourceWhale or Reply.io.
The Email Finder and the Email Verifier cover two distinct steps that are worth measuring separately. Finding an address doesn't guarantee it is valid, relevant or usable in a campaign. The team should track the rate of valid data and replies, and review the legal basis and the opt-out process.
Pros: an attractive cost-to-volume ratio for email, public credit-based pricing and easy integration.
Cons: an email-centric focus, limited LinkedIn automation and less specialisation in multichannel recruiting.

How to choose and migrate without breaking your sourcing process
The best alternative depends on which piece is failing. If the team takes too long to identify and prioritise profiles, start with AI sourcing and advanced filters. If it already has a solid base but loses opportunities through poor follow-up, the problem is in outreach. If it finds candidates but can't reach them, it needs enrichment. And if it maintains conversations over months, it needs a talent CRM or a nurturing layer.
An operational decision matrix
AI sourcing and advanced filters: HeyTalent and hireEZ are the options closest to an AI-based search, prioritisation and contact flow. HeyTalent focuses on extraction, customisable filters and enrichment within the same process. hireEZ adds a pronounced enterprise orientation through integrations and security documentation. Gem also incorporates AI, but its main value lies in the ongoing relationship with talent.
Multichannel outreach: SourceWhale and Reply.io fit when email, LinkedIn, calls, SMS or WhatsApp have to coexist in one cadence. SourceWhale is better adapted to recruiters and agencies, while Reply.io offers a broad multichannel structure with LinkedIn actions. Apollo.io can serve for email and call cadences, but it requires adapting the flow to recruiting.
Contact enrichment: Lusha and ContactOut are useful once the recruiter already has a list of profiles. Snov.io is practical for an email-centred process, while HeyTalent combines enrichment with filters and outreach. The choice should weigh email and phone separately, rather than assuming that a tool which finds emails will have the same phone coverage.
Talent nurturing: Gem is the option most clearly oriented towards communities, recurring campaigns and pipeline analytics. SourceWhale can also cover follow-up, particularly in agencies that combine candidate relationships with business development.
Pricing and transparency
Public pricing makes it easier to compare Apollo.io, Lemlist, Reply.io, Lusha and Snov.io, although you still have to review what each plan includes, how credits are consumed and what happens when limits are exceeded. ContactOut, hireEZ, Gem and SourceWhale work on quotes or proposals, so your request should ask for a breakdown of users, modules, contacts, exports, integrations, support and lock-in.
The cost of the stack isn't just the licence. In Spain, one analysis for agencies puts LinkedIn Recruiter at around 10,000 to 15,000 euros a year per licence, Sales Navigator between 900 and 1,500 euros a year and a basic five-user stack between 900 and 1,500 euros a month. Those reference points appear in the guide to recruitment tools for agencies in Spain, and they show why an apparently cheap tool can stop being cheap once you add the ATS, email discovery, automation and manual work.
