Sync clients to Mailchimp or Brevo

Updated 2026-09-30 · 2 min read

If you send newsletters with Mailchimp or Brevo, Lorenly can keep your audience there up to date with your clients, so you never export and import lists by hand.

Only clients who agreed#

Lorenly only sends clients who gave marketing consent and have an email address. Everyone else stays in Lorenly. Consent is collected by the opt-in box on your booking page, or ticked on the client's record when they agree in person.

Connect Mailchimp#

1. In Mailchimp, create an API key and find your Audience ID (Audience, Settings, Audience name and defaults).
2. In Lorenly, go to Settings → Connect accounts↗ and open Mailchimp under Email marketing.
3. Paste the API key and the audience ID, then choose Test connection.
4. Choose Sync now for the first sync.

Connect Brevo#

1. In Brevo, create an API key and note your list ID (Contacts, Lists).
2. In Settings → Connect accounts↗, open Brevo under Email marketing.
3. Paste both, Test connection, then Sync now.

Each card has a Setup guide with the same steps.

After that#

• Lorenly syncs automatically about once an hour. Sync now runs it immediately and shows how many contacts were synced and when.
• Contacts are added or updated by email address with their first and last name. Lorenly never deletes contacts from your list.
• Unsubscribes are handled in Mailchimp or Brevo. Update the client's consent in Lorenly too so they stay out of your Lorenly campaigns.
