Backfill · Turn blog posts into welcome emails

Newsletter backfill generator: transform your existing blog posts into a welcome/onboarding email series. No more empty inboxes for new subscribers.

Generate your series

The empty inbox problem

New subscribers join your newsletter, but they have nothing to read. Your best content is buried in old blog posts. Manually curating a welcome series takes hours. Backfill solves this.

Before Backfill

New subscribers see nothing in their inbox
You manually pick 5-7 blog posts for a welcome series
You rewrite each post as an email (formatting, tone, CTAs)
You set up sequences in your email tool
Hours of work, and it’s outdated in 6 months

With Backfill

Connect your blog (RSS, WordPress, or paste URLs)
Backfill picks your best posts and converts them to emails
Each email is formatted, personalized, and sequenced
Export to ConvertKit, Mailchimp, or any email tool
Done in minutes, update anytime
