How to Verify Emails in Attio

People View Setup

Attio exports the current view, so the quality of the export depends on the filters and columns you set before clicking Export view as CSV.

Why Verify Your Attio Contacts

Attio is a modern, data-driven CRM that builds much of your contact graph automatically. By syncing connected inboxes and calendars, Attio creates and enriches People records from the activity it observes, and that automation is exactly why the People object accumulates addresses nobody ever deliberately checked. Add the developer API, automations, web form captures, and migrations from a previous CRM, and an Attio workspace ends up holding a mix of solid contacts and quietly unreachable addresses.

Attio does not test whether a Person's email works

The email attribute on a Person record holds whatever value Attio captured or you entered. It might be a typo from a manual entry, an address auto-pulled from a single email thread, an abandoned mailbox from an old migration, or an address that was never valid. Attio stores it without ever opening a connection to the mail server to confirm it is reachable. VeriMails runs that live test, so you can see which People records would bounce before you run a sequence or push the list into a sending tool.

Contact data decays faster than automatic enrichment can fix

B2B contact data goes stale at roughly 2.1 percent per month, which compounds to around 22.5 percent a year, and close to 30 percent of B2B records become unreliable within twelve months as people change jobs and companies restructure. A Person added to Attio a year ago from an email thread or an import has a real chance of being unreachable today. Because Attio enriches contacts continuously, it is easy to assume every record is current when the underlying mailbox may have closed months ago. Verifying an export right before outreach reflects the current deliverability of each address.

Bounces damage the sender reputation behind your workspace

When you sync Attio People to a cold outreach platform or an email tool, every invalid address turns into a bounce. Mailbox providers read a high bounce rate as a signal that a list is low quality or purchased, and they respond by routing more of your mail to spam. A bounce rate above 3 percent needs attention, and above 5 percent it does lasting damage to your sending domain. Verifying first keeps bounces low and protects deliverability for every deal in your Attio pipeline.

Clean People data keeps your Attio reports honest

Attio reports, lists, and workflow automations all assume the People you contact can actually receive mail. Unreachable addresses inflate your record count, distort engagement and pipeline metrics, and trigger workflows that fire follow-up steps against people who never received the first message. Because Attio is often the main record system for a fast-moving sales team, verifying the list keeps that record system grounded in contacts who genuinely exist.

What VeriMails Checks

VeriMails runs every address from your Attio export through a layered set of checks. Each layer catches a different category of bad email, and every Person comes back with a definite status rather than a vague score.

It starts with syntax validation to catch malformed addresses, including the typos that slip in through manual entry on a Person record. MX and DNS checks then confirm the domain exists and is configured to receive mail. The live SMTP handshake is the step that matters most: VeriMails opens a real connection to the receiving mail server and confirms the specific mailbox will accept a message, without ever sending one. This is what catches the abandoned mailboxes and departed contacts that Attio still lists as active People.

VeriMails also runs catch-all detection to flag domains that accept every address whether or not a real mailbox exists, disposable detection for temporary throwaway inboxes, and role-based detection for generic addresses such as info@ or sales@. Catch-all status is reported as a clear detection result, never a probability score. Across all of these checks VeriMails returns clear verification results that work well in live workflows.

Pricing for Attio Users

Verification is priced so that cleaning an Attio People list before outreach costs very little against the value of protected deliverability. Credit packs start at $0.0019 per email, which is $19 for a 10,000-credit pack. Credit packs scale up to 5 million verifications for $1,499, and credits never expire, so a balance bought for one campaign carries forward to the next.

If you export and clean Attio data on a regular cadence, monthly subscriptions are available from $15 per month for the Starter plan with 10,000 credits up to $299 per month for the Agency plan with 1.5 million credits. Every new VeriMails account also includes 100 free credits with no credit card required, which is enough to verify a sample of your Attio People and see how many records hold invalid or catch-all addresses before you commit to a plan.

Workflow Visual

Use this flow when Attio lists need a clean People export and a controlled import back into the object.

• CRM hygiene: Add Attio exports to a recurring CRM hygiene schedule before major launches.
• Bulk cleanup: Use bulk email verification when a saved People view has hundreds or thousands of addresses.
• Adjacent guides: Compare this flow with Folk and Pipedrive if records move between CRMs.

Step-by-Step

What to Do With Each Result

Use the VeriMails result as an Attio operating field so every saved view, workflow, and sync can filter on current deliverability.

• Valid Update the Person, set a verified date, and keep the record eligible for outreach or downstream syncs.
• Invalid Suppress from sending lists and create an owner task to confirm a replacement address.
• Catch-all Keep in a review segment and use only for higher-value accounts with careful send limits.
• Disposable Remove from CRM-driven outreach because the inbox is temporary and unlikely to represent a stable contact.
• Role-based Keep for account-level routing where useful, but exclude from personalized Person sequences by default.
