Should You Back Up Your Site via Email?

Plugins like BackWPup let you back up your site by sending a zip file by email. In most cases, it’s better to use an alternate storage method like FTP or Dropbox.

That’s because backups that are sent via email are often too big to be delivered. Either the email provider has a sending limit, or your mailbox has a maximum file size that it’ll accept. Either way, your emails will fail. This can make it look like your backups aren’t working at all.

If you must use email to receive backups, we’ll show you how to fix deliverability problems in this tutorial. We’ll also show you how to store every email attachment sent from your site, including the zip files created by your backup plugin.

How To Fix BackWPup Not Sending Email

1. Check Backup Job Settings in BackWPup

If you’re using BackWPup to get backup files via email, let’s check the backup job settings first.

Go to BackWPup » Jobs and click Edit under the backup job you want to look at.

open the backup job email settings

In the General tab, uncheck anything that you don’t need to receive. In most cases, it’s a bad idea to try to get all of these items in 1 email because the resulting file will be too big.

Next, scroll down and under the Job Destination, make sure the Backup sent via email option is selected.

That’s it for the General settings. Now, switch to the Schedule settings from the top bar.

Schedule Settings

Here, we need to check that you’ve selected one of the cron schedules. If you select Manually only, the backups will only run when you trigger them.

Next, scroll down and adjust the scheduler settings.

Next, switch to the To: Email tab from the top bar.

Email Sender Settings

This section lets you specify the email recipient for the backups. If you want, you can enter multiple email addresses separated by commas.

Now, scroll down to check the sender’s email settings.

For the maximum file size, set it to 0 which means unlimited. While this will prevent your backups from failing, keep in mind that most email providers have a limit on the size of attachments they’ll accept.

Right at the end, make sure the email sending method is set to Use WordPress settings. This is important: it means we can use WP Mail SMTP to override the default method of sending emails from BackWPup in the next step.

If a different option is selected in Sending method, WP Mail SMTP may not be able to control emails from BackWPup.

That’s it for the email settings. Save the settings here.

Next, let’s fix your WordPress emails with WP Mail SMTP.

We already talked about attachment size limits. Let’s look at that in more detail. If you want to send email attachments from WordPress, this is going to be an important consideration.

Here’s a quick guide to give you an idea of the size limits and fees for each provider:

Provider Attachment size limit Fee for attachments
SendLayer 25 MB
Brevo 4 MB 15 MB
Amazon SES 10 MB by default, up to 40 MB by request $0.12 per GB
Gmail / Google Workspace 25 GB
Mailgun 25 MB
Microsoft 365 / 50 MB / 34 MB
Postmark 10 GB
SendGrid 30 GB
SparkPost 20 GB
Zoho Mail 20 MB
Other SMTP Varies

As you can see, the size limits vary considerably between different providers. You’ll want to factor in these limits along with your own mailbox limits to decide which one is going to work best.

Once you’ve made your decision, use the links below to open our documentation. The docs here will help you to set up a connection between your website and the mailer service you’ve chosen:
