- Double-click the text block to edit it, then highlight the text you’d like to add a link to.
- Click the Add link icon in the text formatting toolbar.
- In the URL field, enter a link to your contact information using one of the formats in the section below.
- Replace the contact information placeholder (e.g., youremail@example.com) with the email address or phone number you'd like your recipients to contact.
- Click Apply to add the link to the selected text.

Link formats for email, SMS, and phone numbers
Link type | Format | Action |
mailto:youremail@example.com | Clicking a link with this address opens the recipient's preferred email app and creates a draft email with your address in the To field. | |
SMS | sms:+19999999999 | Clicking a link with this address opens the recipient's text messaging app with a draft text addressed to your phone number. |
Phone number | tel:123-456-7890 | Clicking a link with this address opens the recipient's default phone call app with your phone number ready to dial. |
Limitations
These links are only supported for certain ISPs and devices. For example, SMS links (i.e., sms:+19999999999) are supported in Apple Mail but are not fully supported in all versions of Gmail, Yahoo, or Outlook. Additionally, recipients who open an SMS or phone number link on a desktop, rather than a mobile device, may not have a messaging or calling app installed. For this reason, it's important to make sure your phone number or email address is visible in the message you send, so recipients can manually type it in if necessary.
Before sending your email, send a test email to your own inbox. Open it on the devices and in the email apps you want to check, then click the contact link to confirm it opens the expected app with the correct address or phone number.
