Most Shopify stores already have an email platform they rely on. Buy Again & Reorder Reminders doesn’t ask you to switch. It connects to the ones you’re probably already using.
Klaviyo
Connect your Klaviyo private API key inside Buy Again and reorder reminders send as Klaviyo events, so they flow into your existing Klaviyo account and templates like any other automated email.
Brevo
Add your Brevo API key and sender details, and Buy Again sends reminders through your Brevo account, using a template it creates for you automatically the first time.
Mailchimp (via Mandrill)
For Mailchimp stores, reminders go out through Mandrill, Mailchimp’s transactional email service, using your sender details and template.
Why this matters
Reorder reminders only work if they get sent, and sent well. By connecting directly to the email platform you already trust, deliverability and sender reputation stay exactly where they are today. No new platform to learn, no separate sending domain to set up, just one more automation running through the tools you already use.
