How to configure email sending signature of your custom domain

A sender signature is a digital authentication method used to verify the credibility of the email sender. It ensures that the email is not a spoof and offers the recipient an additional layer of security.

Thus, it helps to create trust, enhance security, and maintain a professional brand image for WordPress transactional emails.

And know that InboxWP offers this cool feature to let you use a custom email sending signature for email marketing purposes, as it ensures 100% email deliverability of your transactional email.

Here, we’ll show where you can find the sender signature option and how to customize it for your email. 

Where to find the “Sender Signature” option

On the InboxWP frontend dashboard, it will appear next to your site’s information.

Here you’ll find two options.

Add domain: If you verify your domain, you can create and send as many emails as you want. For example, your domain name is “” After adding it, you’ll be asked to verify it. Once you verify it, you can create different email signatures related to this domain.

Such as [email protected], [email protected], etc.

Add a signature: If you add a specific signature, only it will send the emails from your site. You should add the “from email” – [email protected]. That means you can only send emails from this email address, not from others.
