Verify your beehiiv subscribers before a big send
beehiiv has no SimpleVerifier connector. Export your subscribers, verify the CSV, then import the invalid ones with a tag. beehiiv filters invalid, blocked and disposable addresses on import itself, so the point of verifying is the addresses that look fine but no longer have a working mailbox.
The workflow
- In beehiiv, open Settings, choose the publication if you have several, and on General Info click Export Data. Under Export Subscribers click Export All Basic Subscribers (email, status, tier) or Export All Subscribers (adds custom fields and stats). Only admins can export.
- Download the file from the email beehiiv sends or from Historical Exports. Download links last 24 hours.
- Upload the CSV on the verify page, signed in; the first 100 checks are free. The email column is found by its header or contents and every other column is kept.
- When the job finishes, download the valid, risky and invalid files. Each keeps all of your original columns.
- In beehiiv go to Subscribers (or Settings) > Import subscribers, upload the invalid file and tick only the email column and a tag column you add, such as invalid-email. Unticked columns are skipped.
- Importing emails that already exist updates those subscribers rather than adding new ones, so the tag lands on the right people. Segment on that tag, then exclude or delete the segment from your next send.
Menu names follow beehiiv’s own help articles, checked 12 Nov 2026: export subscribers, import subscribers. Vendors rename menus, so trust what you see on screen if it differs. SimpleVerifier is not a beehiiv partner and has no beehiiv connector.
Columns to map
- Email, the identifier beehiiv matches existing subscribers on.
- A tags column with no unescaped commas; beehiiv uses the column to apply tags.
- Custom fields are case-sensitive and some names are reserved by beehiiv. Rename a reserved column before importing.
What to do with risky and catch-all results
On a growing newsletter, risky is mostly catch-all company domains and role addresses. Do not delete risky subscribers: tag them and watch their open rate over two or three issues. beehiiv bills by subscriber count, so removing confirmed-dead invalid addresses saves money, but removing risky ones on a guess does not.
What people use it for
- Clean a list that came from a giveaway or a referral push before opening a paid tier.
- Check a migration import from another newsletter platform before the first beehiiv send.
- Find out how many subscribers have a dead mailbox before you quote a list size to a sponsor.
Using the result
Each address comes back valid (the mail server confirmed the mailbox), risky (delivery could not be confirmed: a catch-all domain, a role address such as info@, or a provider that hides mailbox status) or invalid (it will bounce, or it is a throwaway address).
Full endpoint reference, error codes and an OpenAPI file are in the API docs. For lists of thousands of addresses, upload a CSV on the verify page instead.
Run your 100 free checks on one list before you switch anything
Export one list’s addresses as a CSV and upload it: the first 100 are checked free in the dashboard, no card needed. Compare the results with what you use now, then decide. Nothing in beehiiv changes until you import a file back.
Common questions
- Which plans include API access for beehiiv?
- API access comes with Pro, Business and Agency, listed on the pricing page; Starter covers CSV verification only. A key on a plan without API access gets a 402 that says so. Each key can make 120 calls a minute.
- beehiiv already filters bad addresses on import. Is verifying still useful?
- beehiiv says it filters invalid, blocked and disposable addresses on import, and it does not list which were rejected. A verification run checks the mailboxes behind the rest and tells you the result per address.
- Is there a beehiiv integration?
- No. There is no connector, so the CSV export and import above is the route.
