Forms & email

Send your site's emails through Mailgun or your own email provider.

2 min readUpdated Nov 3, 2026

Before you start

Sites hosted with 1ClickWebsite already send form emails, so you usually only need this if you moved your site to your own hosting or want to send from your own email service. To change which inbox gets submissions, use Set up contact form emails instead.

Have these details from your email provider ready: SMTP host, port, encryption type, username, password, and the sender email and name. We recommend Mailgun.

Good to know: this one has to be done in WordPress, because the Website Agent can't install plugins. For edits to your pages, text or design, ask the agent instead.
