Switching from Mailchimp to Postbird is mostly a matter of following the same three steps every OneTimeSuite app uses — buy once, deploy or install, bring your workflow over.
Step 1: Buy once on Whop
One-time $59 for the packaged version — no per-contact pricing, no subscription to escalate as your list grows.
Step 2: Plug in your SMTP
Amazon SES ($0.10 per 1,000 emails), Postmark or Mailgun credentials. You inherit their deliverability reputation; Postbird handles the queue and throttle.
Step 3: Import, build, send
CSV-import your list, drag blocks into an email, and send throttled campaigns with live progress and open/click reports.
What to expect during the switch
Postbird covers the same core workflow as Mailchimp, so most people are productive within the first session — see the full feature list and FAQ on the product page before you commit.
Why make the switch at all
Mailchimp runs $20+/mo (grows with your list), forever. Postbird is $59, once. At 1,000 contacts, Mailchimp Standard costs more than Postbird every three months, forever. Break-even is ~2 months — and the bigger your list gets, the more you save.
Try Postbird — $59, once
Lists, segments, a drag-block builder, throttled sending & open/click tracking — no per-contact pricing.
