Verify an Adapt.io Export Before You Send

What Adapt.io says

From Adapt.io's pricing page, read 9 November 2026:

• The page offers to "Find verified email addresses from anywhere online" with its Email Finder extension and calls its data "verified and accurate B2B data".
• Free: 25 email credits and 25 enrichment credits. Starter at $49 a month: 500 email and 500 enrichment credits. Basic at $99 a month: 1,000 email, 1,000 enrichment and 100 phone credits. Custom plans on request.
• CSV export is listed on Starter: "Download your contacts to a spreadsheet and import them in to your CRM and outreach platforms."
• CRM export on Basic goes to Salesforce, HubSpot, Pipedrive, Zoho, Outreach and Salesgear.
• Pricing is "based on number of contact credits and not number of user licenses". A 7-day free trial is offered with no card.

The page does not list the status values an export carries or how often addresses are re-checked, so this guide treats every address in the file as unconfirmed until you check it.

Why a Adapt.io row can still bounce

• Unknown check age. Without a stated refresh cycle, you cannot tell which rows are months old (email valid but person left the company).
• Catch-all domains. Finder tools cannot confirm a mailbox on a server that accepts everything (catch-all emails: what to do).
• Browser-extension finds. Addresses found from a page can be guessed from a pattern rather than seen.
• Merged files. Adapt.io rows loaded next to an older list. The oldest rows set your bounce rate.

The send-day routine

1. Export and note the date

Add an export-date column so you can re-verify by age later. Keep the original file untouched and work on a copy.

2. Clean

• Remove duplicate emails across every file you are loading.
• Limit contacts per company so one account does not get a burst.
• Tag catch-alls with the bulk catch-all checker.

3. Verify

Upload the CSV at /verify, pick the email column and run it. Each address gets a live SMTP check.

Result	Action
Valid	Main sequence
Risky (catch-all)	Second wave, best grades first
Risky (role, disposable, full)	Drop for outreach
Invalid	Suppress
Unknown	Re-check tomorrow

Catch-alls come back as risky with a grade and a reason (catch-all scoring).

4. Re-import and send in waves

Download the results, keep valid rows for your main sequence and load them into your sender. Catch-alls go a day later in a small batch. Pause when hard bounces pass your platform's line (bounce rate thresholds by platform).

5. Compare against your own numbers

Note the bounce rate by source. If Adapt.io rows bounce less than other sources after your own check, that is evidence worth more than any pricing page. Bounce rate by source helps compare.

What to do with each group

Valid rows go into the main sequence, with the verification date kept in a column.

Risky catch-all rows are the judgment call. The server accepts anything during the check, so the best you get is a grade and a reason. Send the best-graded ones first, a day after the valid wave, and stop if bounces rise.

Risky role, disposable and full-mailbox rows are poor outreach targets.

Invalid rows go to a permanent suppression list so they never return in a later import (cold email suppression lists).

Unknown rows mean the server did not answer in time. Retry the next day.

Credits you already paid for

Spending finder credits and verifying are separate jobs: the first finds an address, the second tells you whether to mail it. Run the check after export rather than before, and only on rows you plan to contact. Enrich then verify covers the order when you use more than one source.

Try it on your own export

Upload a slice at /verify. The first 100 checks are free with a Google sign-in, no card.

Pro, $39 a month: Unlimited email verification.* Never metered, never cut off. See pricing.

*Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.
