Findymail Clay Integration: How to Use Findymail Inside Clay

Yes, Findymail works inside Clay. Clay lists Findymail as a Clay-built data provider with actions such as Find Work Email, Find Work Email from Profile URL, Verify Email and Find Mobile Phone, and you can run them on Clay credits or with your own Findymail API key. What we could not confirm is whether Findymail sits in Clay's default email waterfall, so this guide shows how to add it yourself and when that makes sense.

Some tool links here are affiliate links (disclosure). If you want to follow along, open Findymail in one tab and your Clay workspace in another. For the full picture of the product (pricing, accuracy claims, pros and cons), read our Findymail review.

Findymail in Clay: the short answer

What the integration includes

Clay's Findymail integration page groups the provider under People Data, Contact Data and Contact Data Verification. It lists seven live actions, and marks four of them "Clay Credits or Bring Your Own Account."

Two naming notes. Clay's docs call the verification action "Validate Email," while the integration page calls it "Verify Email," so search for either. Clay's docs also price only the four main actions, so check the action panel in your table for the other three before you run them at scale.

Where Findymail's own claims fit

Findymail says its emails are verified in real time when you request them, and that it validates catch-all addresses that other tools tend to mark risky. It also says it guarantees a bounce rate under 5%, with credits refunded if you exceed it. Those are Findymail's claims; see the full Findymail review for how they hold up against what is published.

Findymail's homepage says it ranked "#1 in email finding accuracy and coverage, per Clay's benchmark." Clay's own "Best work email provider by region 2025" page (last tested October 22, 2025) lists Findymail with data quality between 90.05% and 96.26% and coverage between 65.19% and 90.26% across five entries. The text we could read did not show which region each entry covers or an explicit rank, so treat the ranking as Findymail's statement.

Clay credits or your own Findymail key?

This is the main decision, because it changes who bills you for each lookup.

Option 1: Clay-managed account

You pick the Clay-provided key and Clay charges its own credits: 2 per found work email, 9 per mobile phone and 1 per validation, per Clay's Findymail docs. You need no Findymail subscription at all. This is the simplest way to test Findymail on a few hundred rows.

Clay's pricing page was hard to pin down on November 9, 2026. It showed "from" prices for Launch and Growth that differed from the headline figures on the same page and from its FAQ, so we are not converting Clay credits into dollars here. Check Clay's pricing page for the current cost of data credits on your plan.

Option 2: Bring your own Findymail account

You paste your own Findymail API key, and Findymail bills the lookups against your Findymail plan. Clay's pricing FAQ says that with your own API key, "Each run will count as one Action, but no Data Credit will be used." So you still use Clay actions, but not Clay data credits.

On the Findymail side, what you pay depends on your plan type, as of November 2026:

Findymail says its usage pool is shared across the web app, extension, integrations and API, and by everyone on the plan. That means a big Clay run draws from the same allowance your reps use in the Chrome extension.

On the Starter credit plan, $99 for 5,000 finder credits works out to about $0.0198 per found and verified email. Usage plans cannot be priced per email because Findymail does not publish the allowance. The pricing section of our in-depth Findymail review walks through which plan fits which volume.

Which one to choose

• Choose Clay credits if you are testing, if your Clay credits are already paid for, or if you only need Findymail as a late fallback that runs on a small share of rows.
• Choose your own key if Findymail is your main email source, if you also use Findymail outside Clay, or if you want misses to cost nothing on a credit plan.
• Watch the action count either way. Your own key saves data credits, not actions, so very large tables still draw down your Clay action allowance.

How to set up Findymail in Clay

These steps combine Clay's Findymail docs with Findymail's help article on Clay (updated September 23, 2023, so labels may have moved since).

1. Get a Findymail API key (own-key route only). Sign up for Findymail (the free account includes 10 credits, no card). Findymail's help article says to create an API key named "Clay" in your account; Clay's docs point to Findymail's API token settings for the key.
2. Open your Clay table and click Add enrichment.
3. Search for "Findymail" and choose an action under Integrations, for example Find Work Email.
4. Pick the account. Choose an existing Findymail account, or click to add one and paste your API key. Findymail's article describes ticking "Use my own Findymail API key" and clicking "Add an account" the first time. To use Clay credits instead, select the Clay-provided key.
5. Map the inputs. For Find Work Email, map a full name column and a company domain column. For profile URLs, use Find Work Email from Profile URL instead.
6. Set run conditions. Clay supports an "Only run if" condition, so the enrichment runs only when your conditions are met, plus an auto-update run setting.
7. Test on a few rows first, then run the column on the full table.

Input tip. Findymail's help article says its email enrichment only accepts "full name + company website or full name + company name." If your table has first and last name in separate columns, add a formula column that joins them before you map it.

Using Findymail in a Clay waterfall

A waterfall tries several providers in turn so that more rows end up with an email. Here is what Clay documents, and what it does not.

What Clay documents

Clay's lesson on enriching people with waterfalls says:

• The email waterfall starts with six providers by default, and "you can customize your waterfall by adding more providers to maximize your email coverage."
• Validation is built in: "Clay's email waterfalls go one step further by including email validation in the waterfall process."
• ZeroBounce is the default validator, and you can choose a different one.
• Catch-all emails count as valid by default, and enabling "only mark safe to send" excludes them.
• The waterfall can keep running after a provider returns an email if that email fails validation.

None of the Clay pages we read named the six default providers, and none placed Findymail in the default list. So do not assume it is there. Open your waterfall and check the provider list.

Pattern 1: Add Findymail as a waterfall provider

Because Findymail is a Clay email enrichment provider, you can add it to the email waterfall alongside the providers you already use. Where you put it is your call; Clay's lesson does not recommend an order for Findymail.

Our reasoning on placement (opinion, not a Clay rule):

• Put it early if you bring your own Findymail key on a credit plan, since misses cost nothing there and Findymail claims strong catch-all coverage.
• Put it after cheaper providers if you pay Clay credits and another provider in your stack costs fewer credits per found email.
• Decide on catch-alls deliberately. Findymail says it validates catch-all domains. Clay's waterfall treats catch-alls as valid by default unless you turn on "only mark safe to send," so pick one rule and apply it to the whole table.

Pattern 2: A standalone Findymail column as a fallback

If you prefer full control, skip the built-in waterfall for Findymail and add a separate Find Work Email column. Use "Only run if" so it runs only when your earlier email column is empty.

This is plain Clay logic built from documented features, and it makes Findymail's cost easy to see because it sits in its own column. It also lets you run a separate Findymail Validate Email column on rows that came from other providers, at 1 credit each on a Clay-managed account.

Pattern 3: Profile URL first, name and domain second

Clay offers two Findymail email actions. If most rows have a profile URL, run Find Work Email from Profile URL first, then Find Work Email (name plus domain) only where the first one returned nothing.

Each action costs the same 2 Clay credits on a Clay-managed account, so the order is about coverage, not price. Findymail's API docs show the same two lookup types as separate endpoints; our Findymail API guide covers them.

Phones in Clay through Findymail

Find Mobile Phone takes a professional profile URL and returns a mobile number. It costs 9 Clay credits per enriched cell on a Clay-managed account, versus 2 for an email.

Two limits apply on Findymail's side. Findymail says phones are not available for EU contacts, and its API docs describe the phone field as US numbers only. Before you run phones on a whole table, filter it with "Only run if" to the rows where a phone is worth the credits, such as US contacts at your top-tier accounts.

Findymail inside Clay or Findymail on its own?

You do not need Clay to use Findymail. Findymail has its own bulk finder, Chrome extension, verifier and native pushes to sequencers. The question is where the rest of your workflow lives.

If your next step is a cold email tool, our guide to moving Findymail contacts into Instantly, Smartlead or PlusVibe covers both the native push and the CSV route.

Should you double-verify Clay output?

Findymail says you do not need to re-verify Findymail data, and that third-party verifiers may flag 15 to 20% of its emails as risky. Clay's waterfall runs its own validator (ZeroBounce by default) on waterfall results.

That can create a disagreement: Findymail marks an address valid, and the waterfall validator marks it risky or catch-all. Our rule is simple. Send the clean "safe to send" rows to your main campaign, and put disputed or catch-all rows in a smaller campaign so any bounce spike stays contained.

Our Findymail email verifier guide explains when a second check is worth paying for.

Is Clay the only way to build this?

No. Clay is the best known table tool for multi-provider enrichment, but others exist. If you are weighing Clay against an alternative, see our Bitscale vs Clay comparison, and if you are deciding between a database tool and a table tool, our Apollo vs Clay breakdown covers that split.

Setup checklist

• [ ] Decide: Clay credits or your own Findymail key
• [ ] If own key, create a Findymail API key (name it "Clay") and connect it under Add enrichment
• [ ] Join first and last name into one full name column
• [ ] Clean company domains (no http, no paths)
• [ ] Run profile URL lookups first if you have URLs, name plus domain second
• [ ] Check whether Findymail is already in your email waterfall before adding it
• [ ] Choose one catch-all rule ("only mark safe to send" on or off) for the table
• [ ] Gate Find Mobile Phone with "Only run if" to non-EU, high-value rows
• [ ] Test on 20 to 50 rows and check cost per found email before the full run

Final take

Findymail in Clay is a real, documented integration, and it is flexible: Clay credits for testing, your own key for volume. The parts to handle yourself are placement in the waterfall, catch-all policy and phone spend, since Clay's docs leave those decisions to you.

If you have not settled on Findymail yet, start with our Findymail review, then try it on a small table with the free Findymail account. When you are ready to scale, compare Findymail's plans against the Clay credits you would otherwise spend.
