Sending form emails through your own email account

Use your own mail server (Gmail, Google Workspace, Microsoft 365 or your web host) so form emails come from your address.

Form emails are sent by XSiteBuilder — or, if you like, through your own email account

Normally contact-form emails are sent by XSiteBuilder. You can send them through your own email account instead: they then come from your own address and are less likely to land in spam.

Set it up

Go to Settings → Email for contact forms (optional):

Filled in for a Gmail account
Filled in for a Gmail account
  1. Mail server (SMTP host) — see the table below.
  2. Port
  3. Security
  4. Username — usually your full email address.
  5. Password — for Gmail, an app password (below).
  6. From address and From name — who the emails appear to come from.
  7. Leave Send a test email … after saving ticked and click Save and test.

We connect to your mail server before saving, so you'll know straight away if something's wrong. Your password is stored encrypted. Only workspace owners and admins can change this, and it applies to every site in the workspace.

Common settings

Provider Server Port Security
Gmail / Google Workspace smtp.gmail.com 587 STARTTLS
Microsoft 365 / Outlook smtp.office365.com 587 STARTTLS
Zoho Mail smtp.zoho.com 465 SSL/TLS
Your web host ask your host (often mail.yourdomain.com) 465 or 587 SSL/TLS or STARTTLS

Gmail and Google Workspace need an app password, not your normal password: turn on 2-Step Verification in your Google Account, go to Security → App passwords, create one, and paste the 16-letter code into Password.

Microsoft 365 mailboxes may need "Authenticated SMTP" turned on by your Microsoft 365 administrator.

Allowed ports are 25, 465, 587 and 2525.

If your mail server fails

If your server rejects a message, we send it through XSiteBuilder instead so you don't miss it. The message on the site's page is then marked "sent via … — your mail server failed", with the reason.

Stop using it

Click Stop using it in the same section. Emails go back to being sent by XSiteBuilder.
