Newsletter signup problems
These issues cost you subscribers and waste hours every week
Subscribers leak between tools
Manual CSV exports from your website to your email service. People slip through the cracks, data gets lost.
Manual syncing hell
Every week you export subscribers, reformat the CSV, import to Mailchimp. One mistake corrupts your list.
No double opt-in flow
Spam emails join your list and tank your deliverability. No confirmation emails, no subscriber verification.
Lost signups during migration
Switching from Mailchimp to ConvertKit? Hundreds of signups get lost because your form still points to the old service.
Simple HTML. Powerful automation.
No backend code, no email service API integration, no confirmation email setup
