Verify your Webflow Forms export before you send
Export your form submissions from Webflow Forms as a CSV, upload it to SimpleVerifier as it is, and every address gets a live mailbox check. You download valid, risky and invalid files with your original Webflow Forms columns kept, ready to import back.
1. Export the CSV from Webflow Forms
- In Webflow, open your site's Forms submissions area.
- Choose the form whose submissions you want.
- Export the submissions as a CSV.
Webflow's help says the CSV holds all submission data for that form and uploaded files appear as URLs. The exact button labels were not confirmed on the help page, so follow the labels you see in the Webflow editor.

Verify your Webflow Forms export3. Import the clean file back
You get three files: valid, risky and invalid, each with every column from the original export. Import the valid file back into Webflow Forms or your sending tool, and keep risky addresses (usually catch-all domains) out of cold sends.

Common questions
- How do I export my form submissions from Webflow Forms?
- In Webflow, open your site's Forms submissions area. Choose the form whose submissions you want. Export the submissions as a CSV. Webflow's help says the CSV holds all submission data for that form and uploaded files appear as URLs. The exact button labels were not confirmed on the help page, so follow the labels you see in the Webflow editor.
- Do I need to change the Webflow Forms CSV before uploading it?
- No. The email column is found by its header or its contents, so the Webflow Forms export works as it is. Every other column is kept, and the cleaned files come back with your original columns so you can import them straight back into Webflow Forms.
- Why verify a list that came from Webflow Forms?
- Subscribers who signed up years ago move jobs, abandon inboxes or typed their address wrong. Every send to a dead address in Webflow forms is a bounce on your sender reputation, and many ESPs bill by contact count, so removing dead addresses also lowers the bill.
- How much does it cost?
- Verification is $29.99 a month with no limit on verifications, for files up to 100,000 rows. See the pricing page for the plans.
