Setting Up Your SendLayer Account

First, you’ll need to set up an account so you can connect your WordPress site with SendLayer. If you don’t have an account yet, see SendLayer’s instructions on creating a new account.

Once you’ve set up a SendLayer account, be sure to log in to your SendLayer dashboard. From here, you can begin the mailer setup, which we’ll cover in the next steps.

Authorizing Your Domain in SendLayer

Before you can send emails with SendLayer, you’ll need to authorize your domain. This process shows email servers that you’re the confirmed owner of your sending domain and that your emails are being sent from a legitimate source.

For step-by-step details on how to complete this process, we recommend checking out SendLayer’s guide to authorizing your domain.

Now that you’ve authorized your domain in SendLayer, you can set up WP Mail SMTP.

When you’re ready to get started, go ahead and log in to your WordPress admin dashboard. You’ll also want to install and activate the WP Mail SMTP plugin if you haven’t already.

In the next sections, we’ll cover the details for each of the settings located on this page.

From Email

The From Email is the email address that all of your WordPress site’s emails will appear to be sent from. For SendLayer services to work properly, this email address must be at the domain you set up in SendLayer.

We also strongly recommend checking the Force From Email box. Selecting this option will prevent you from having to edit the From Email settings in other areas of your site.

From Name

The From Name will be set to your site’s name by default. However, you can change this to any text you’d like.

You can also select the Force From Name option to apply this setting to emails site-wide.
