Contact form best practices for email deliverability

Updated on July 14th, 2021

Finding out that your contact form submissions are not reaching their destination can be frustrating. Try these tips to ensure deliverability!

Table of Contents:

1. From address
2. Reply-to address
3. Authenticate your domain

From address

Emails are best sent with a from: email address that matches your site’s domain. Trying to send from an email address that doesn’t include the domain could be interpreted as email spoofing. Even if you haven’t set up a particular email address for your domain, like [email protected] for example, the email will still send.

Use a full email address in the from: field rather than a shortcode. For example, [email protected] is better than using “[admin_email]” or “{admin_email}”. However, shortcodes in the message body are typically ok.

Hotmail, AOL, etc. email addresses should never be used for the from: email address.

It’s not ideal to use the from: address as the form submitter.

Reply-to address

When using reply-to:, the email address should be different than the from: email address. In some cases, this can raise the possibility of the message being flagged as spam.

Authenticate your domain

If you are utilizing Flywheel’s built in mail sending through Sendgrid, you can improve email deliverability by setting up email authentication. Check out this article for instructions: How to authenticate your email with SendGrid
