A website needs three kinds of messaging plumbing: forms people fill in, email your site sends, and a newsletter list. All three are built in — you bring the API keys for the providers you choose.
Forms
Add a form to any page from the editor's block picker. The Form block connects to Sendl — build the form there (contact, signup, survey, quiz), then pick it from the list in the editor and it renders inline on your page. Submissions, spam protection, notifications, and analytics are handled by Sendl; connecting takes one API key in Settings.
Claude can do this end-to-end too: ask it to build a form and place it on a page, and it will.
Transactional email
Order confirmations, password resets, and form notifications are sent through an email provider you configure in Settings:
- Mailjet — API key + secret.
- Postmark — server token. Known for excellent deliverability.
- SMTP — any SMTP server you already have.
Set your from address and name in the same place. Use an address on a domain you control — email sent "from" a domain that isn't verified with your provider tends to land in spam.
Newsletter signups
Paste a Mailchimp API key and audience ID in Settings, drop a subscribe block on any page, and signups flow into your Mailchimp audience automatically. Marketing email and transactional email stay separate — which is how deliverability people will tell you it should be.
Where notifications go
Admin notifications (like new orders) go to the recipient addresses configured in Settings — you can set separate recipients for general notices and order notices.
