Connect your email marketing tool

Marketing → Email tool (/marketing/email-tool). Supported tools: iResendly, Mailchimp, Klaviyo, Brevo and Omnisend.

1. Click Connect on your tool's card and paste its API key (steps below). SellOrchard checks the key with the tool.
2. Choose the list / audience new subscribers go to (Omnisend has no lists — contacts go to the store).
3. Options: Sync newsletter subscribers (on by default), Sync all customers (off by default; customers who didn't agree to marketing are added as non-subscribed / transactional contacts, never as subscribers), Sync segments as tags (on by default), Send order events (Klaviyo and Omnisend: a "Placed Order" event for flows).
4. Save: everyone is sent once (progress shows "N of M"), then every change syncs within a minute or two: new signups, customers, unsubscribes from your email links, orders. Sync now sends everyone again; Pause stops syncing (changes wait and go when you resume); Disconnect stops syncing and deletes nothing in your tool. The Sync log lists recent changes with errors.

• If the tool rejects the key (revoked or lost access), the status turns to Error, syncing pauses and you get a notification and an email: paste a new key to resume.
• Unsubscribes in your email tool are respected by your tool (SellOrchard doesn't import them back).
