Why agencies pick Mailsfinder

A program built around how agencies actually buy data

Three pricing realities that change the math for any agency running outbound across more than one client.

person_off

No per-seat fees, ever

Apollo charges $49 per user per month. ZoomInfo adds per-seat fees on top of a five-figure base. Mailsfinder charges per workspace. Every strategist, VA, and outbound manager on your team can pull data from the same credit pool with no licensing math.

payments

Lowest per-credit cost in the category

Monthly works out to $0.0000333 per email. Lifetime drops that to $0.000125 across the full 2M pool. Hunter runs $0.0245 per credit on Pro. Apollo and ZoomInfo per-credit math is locked behind sales contracts that almost always come out higher.

api

REST API for client-specific workflows

Finder, Verifier, and Enrichment endpoints are included on Monthly and Annual. Lifetime ships Finder and Verifier. Wire client-specific automations into n8n, Make, or Zapier without paying API surcharges or hitting low-tier rate limits.

When a client campaign suddenly needs 80K extra contacts, layer a credit pack on top of any plan. Packs never expire and stack on top of the subscription pool.

Real agency workflows

How agencies actually use Mailsfinder across clients

Four real flows pulled from agencies running between two and twelve clients on a single Mailsfinder workspace.

Client A workflow

Apollo export to Mailsfinder verify to Smartlead

SaaS client wants 20,000 verified leads per month. The agency exports raw contacts from Apollo, runs them through the Mailsfinder Verifier API to drop catch-all and risky rows, then pushes the clean list into a dedicated Smartlead mailbox set up for that client only.

Client B workflow

LinkedIn Sales Nav to Mailsfinder find + verify to Lemlist

Link-building agency scrapes editors and content managers from Sales Navigator weekly. Mailsfinder finds the work email from each LinkedIn URL, verifies it in the same pass, then pipes verified contacts directly into Lemlist for outreach.

Client C workflow

Inbound HubSpot leads to Mailsfinder enrich via Zapier to CRM

Recruitment agency has inbound applicants landing in HubSpot. A Zapier flow calls the Mailsfinder Enrichment API to attach company size, role title, and a verified personal-domain email so account managers see a full picture before calling.

Client D workflow

Bulk list scrub before send via Mailsfinder API

Growth agency receives client-provided lists every Monday. Each list goes through a Mailsfinder Verifier batch via the API, then the agency returns a "list quality report" with deliverable counts, bounce-prone rows, and a clean exportable CSV ready for the client's ESP.

Per-credit math

What does an email actually cost you?

A straight per-credit comparison across the tools agencies stack today. Lower is better.

Tool / Plan Credits Price Cost per email
Mailsfinder Monthly 300,000 / cycle $9.99 / mo $0.0000333
Mailsfinder Lifetime 2,000,000 lifetime $249 once $0.000125
Hunter Starter 500 / mo $49 / mo $0.098
Hunter Pro 5,000 / mo $149 / mo $0.0298
Apollo Basic Limited credits + per-seat $49 / user / mo Per-seat math escalates fast
ZoomInfo (sales contract) Custom credit cap $20K+ / year typical Highest per-credit cost in category

Competitor pricing pulled from public website tiers. Apollo and ZoomInfo are bundled with platform features that add value beyond raw data, so the comparison is purely cost per verified email, not feature parity.

What agencies tell us they need

The honest gap list, and what is on the roadmap

Mailsfinder is not the right pick for every agency yet. Here is what the product does not do today, what we are building, and what is already worked around in practice.

cancel

No built-in multi-tenant dashboard (yet)

There is no per-client view inside the app today. Agencies tag exports by client filename or route through separate API keys. A native multi-tenant view is on the 2026 roadmap.

cancel

Credit pool is shared across clients

One pool covers every client campaign. Agencies that need hard credit isolation per client usually open a second workspace or pass through credit costs in their service agreement.

cancel

No white-label reporting

CSV exports are unbranded, but a fully branded in-app client report is not shipped. Most agencies build a Looker Studio or Google Sheet over the API for branded delivery.

schedule

On the roadmap

Per-client workspaces, white-label reporting, and an agency billing dashboard that tracks credit usage and revenue per client. Lifetime customers and 6+ month commits get early access.

Agency FAQ

Eight questions agency owners ask before signing up

Can I run multiple clients from one Mailsfinder account? expand_more
Yes. Mailsfinder bills per workspace, not per client or per seat. One Monthly plan at $9.99/mo gives the agency 300,000 credits per cycle to spend across every client campaign. Most agencies tag exports with a client prefix in the CSV filename so usage is easy to track internally.
Do you offer a multi-seat or team plan? expand_more
Mailsfinder does not charge per seat on any plan. The credit pool is shared across the workspace, so strategists, VAs, and account managers can all pull data without seat licensing. There is no separate team tier because every paid plan already behaves like one.
Can I white-label reports for clients? expand_more
CSV exports are plain data files with no Mailsfinder branding, so agencies can rename columns and hand them to clients directly. Native white-label reporting dashboards are not built into the product yet. Most agencies build a custom Looker Studio or Google Sheet on top of the API for branded delivery.
How do agencies typically structure credit usage across clients? expand_more
The credit pool is shared, so agencies usually track per-client usage by naming convention (e.g., client-a_finder_2026-06.csv) or by routing each client through a separate API key tag. For agencies that want hard isolation, a separate Mailsfinder workspace per client is the cleanest pattern.
Do you offer agency-specific discounts or volume pricing? expand_more
Standard pricing is already structured for agencies: Monthly at $9.99 for 300K credits, Annual at $7.99/mo billed $95.88/year, and Lifetime at $249 one-time for 2,000,000 credits. Agencies committing to 6+ months can book a call for dedicated onboarding and volume credit packs.
Is there an affiliate or referral program for agencies? expand_more
Yes. Mailsfinder runs a referral program with recurring commissions for agencies that refer paying customers. Sign up by booking a call and the team will share the affiliate dashboard and tracking links.
Can I migrate from Apollo, Hunter, or ZoomInfo? expand_more
Most agencies switch over by running their existing Apollo or Sales Navigator exports through Mailsfinder for enrichment and verification. The Mailsfinder API is documented and slots into the same n8n, Make, or Zapier flows used with Hunter or Apollo, so migration usually takes a single afternoon.
Do you offer dedicated onboarding? expand_more
Agencies on Lifetime or any plan with a 6-month commitment get dedicated onboarding from the Mailsfinder team. That includes API integration help, workflow review, and a priority WhatsApp channel for time-sensitive client questions.

Stop paying per seat. Start with $9.99/mo or grab Lifetime for $249.
