Bring your list in one upload.
Export your audience from Mailchimp and upload the file. Your contacts, names, and tags come over in one step, and everyone who unsubscribed stays unsubscribed.
Start free: 1,000 emails a monthNo card. Importing your list doesn’t use any of your sends.
How the move works
Export from Mailchimp
Export your audience. Mailchimp gives you a zip file with a spreadsheet for each kind of contact: subscribed, unsubscribed, cleaned, and sometimes non-subscribed.

Upload the zip
Drop the zip (or the CSVs inside it) on the import screen. Hollerpost recognizes a Mailchimp export and maps the columns for you. Non-subscribed people never agreed to marketing email, so they’re left out.
Check the summary
You’ll see something like “Imported 2,412 contacts, 3 tags, 311 unsubscribes kept as do-not-email.”
What comes over
- Email addresses, first and last names
- Tags
- When each person originally signed up
- Unsubscribed and cleaned addresses, kept as do-not-email so nobody who left hears from you again
What stays behind
The import moves your people, not your designs. Email templates and automations you built in Mailchimp don’t come across, so plan on rebuilding the few you use. The AI writer makes that go faster than you’d think.
What switching saves
Same list, same sending, monthly prices.

| 500 contacts | twice a month (1,000 emails) | $13/mo | $0/mo (Free) | $13/mo less |
