Lovable: Connect Your App to Mailjet

LovableView original changelog

Lovable added a Mailjet connector so apps can send transactional email, add contacts to Mailjet lists, and read delivery status such as sent, opened, clicked, or bounced. It works in project chat and in published apps. Lovable recommends Lovable Emails for standard cases and Mailjet for teams that already manage sending or contacts there.

Key Takeaways

  • Lovable apps can now send transactional email through Mailjet, from a sender or domain already validated in Mailjet.
  • Apps can add contacts to Mailjet lists and read delivery status (sent, opened, clicked, bounced), which enables delivery dashboards.
  • Lovable still recommends Lovable Emails for standard transactional email, positioning Mailjet for teams with existing Mailjet sending or higher volume.
  • Setup needs an API key, secret key, and region; a 401 on verification usually means the wrong region was chosen.
  • The connector cannot verify domains, handle SMS, or receive Mailjet webhooks, so those stay in Mailjet or in the app's own backend.
  • Keys are not rotated automatically and each connection maps to one Mailjet account shared across linked projects.

Mailjet joins Lovable's app connectors

Lovable added a Mailjet app and chat connector on November 9, 2026. Mailjet is an email delivery service. The connector lets a Lovable app send transactional email from a sender or domain validated in Mailjet. It works both in the project chat and in published apps.

What the connector does

Apps can send transactional email, add contacts to Mailjet contact lists, and read delivery status such as sent, opened, clicked, or bounced. They can also list the senders in a Mailjet account. Lovable suggests order confirmations, newsletter signups, and delivery dashboards.

Lovable's own docs point standard transactional email to Lovable Emails. Mailjet makes sense when a team already manages sending or contacts there, or needs more volume.

Setup

A person needs a Mailjet account, a sender address or domain validated in Mailjet, an API key with its secret key, and the API region for the account. In Mailjet they open API Key Management and copy the primary key and secret. In Lovable they open Connectors, select Mailjet, click Connect, and enter the key, secret, and region. If verification fails with a 401 error, the docs suggest trying the other region. Lovable verifies the keys before saving. The connection is then linked to projects, either from its settings or by asking Lovable in chat.

Limits

  • The connector cannot validate senders or configure DNS, so domains must be verified in Mailjet first.
  • It covers email only, not SMS.
  • It does not receive Mailjet event webhooks.
  • API keys are not rotated automatically.
  • One connection uses one region and one Mailjet account, shared by all linked projects.

Mailjet bills email usage directly, not Lovable. On Business and Enterprise plans, creating connections depends on admin settings.
