Why Allowlist WP Mail SMTP?

Email providers sometimes block emails that are sent from a mailing list. If you’re already using WP Mail SMTP, you might have noticed how aggressive these spam filters can be!

We definitely think spam filtering is a good thing for the whole internet. But it’s not perfect, and it sometimes blocks messages that you actually want to receive.

By adding us to your allowlist, you’re telling your email provider that it’s OK to deliver our emails to your inbox. So next time we send email about our sales, giveaways, and announcements, you’ll be the first to know!

What Is an Allowlist?

An allowlist is a list of email addresses that you’ve manually set up as ‘trusted’ senders in your email account.

Any emails from an address on your allowlist won’t be filed as spam.

It’s an easy way to override spam filters and signal to your email service that these emails are trustworthy senders.

The awesome thing is that these filters actually influence email servers across the whole internet. When you add an email to your allowlist, other providers will recognize that address as a legitimate sender too.

So by adding us to your allowlist, you’re helping out other people who want to get emails from WP Mail SMTP!
