How to Migrate from Sailthru to Sequenzy

Step 1: Export Your Subscriber Data

Export your subscriber list from Sailthru including email addresses, names, tags, custom attributes, and engagement data. Work with your Sailthru account team if needed.

Step 2: Create Your Sequenzy Account

Sign up at Sequenzy and connect your Stripe account. This automatically syncs subscription data, MRR, and churn signals.

Step 3: Set Up Domain Authentication

Add DNS records for SPF, DKIM, and DMARC. Sequenzy provides the exact records during onboarding.

Step 4: Import Your Contacts

Upload your export to Sequenzy. Map email addresses, names, tags, and custom attributes. Sequenzy supports unlimited contacts on all plans.

Step 5: Recreate Email Automations

Rebuild your email workflows in Sequenzy. Use AI sequence generation to create email content faster. Note that Sailthru's content personalization and interest graph features won't transfer — focus on the email automation workflows.

Step 6: Accept Feature Tradeoffs

Predictive content recommendations, interest graphs, and multi-channel (SMS/push) won't be available. If these were core to your strategy, Sequenzy may not be a full replacement. If you primarily used Sailthru for email, the savings are substantial.

  • No automated content recommendations: Cannot suggest content based on reading behavior.
  • Email only: No SMS or push notifications.
