Tips

  • MailerLite is built for email marketing. It excels at newsletters, subscriber management, and automation. For transactional emails like password resets, pair it with Resend or SendGrid.
  • Free tier includes 500 subscribers and 12,000 emails per month. A solid starting point. Upgrade as your list grows.
  • API token permissions matter. Generate a token with the permissions your app needs. Read-only tokens cannot add subscribers or send emails.
  • Manage subscribers in MailerLite. You can add subscribers through Rocket, but removing subscribers, managing unsubscribes, and editing groups must be done in the MailerLite dashboard.
  • One MailerLite account per project. Each Rocket project connects to one MailerLite API token.
