Is it better to use a WP SMTP plugin or the SMTP addon from Cloudways?


Hi Lucash, thanks for the info. For me that is not a solution, because I have 2 sites on a single server and both sites need different SMTP settings. The SMTP addon with Cloudways combined with the plugin as you suggest works, but is configured per server, not per application.

I think there is no real solution to the slow e-mailing with Office 365, I think it is related to Office 365 and not really to Cloudways anyways. However, I have a nice workaround you could try if you have multiple applications and need different settings per application.

The workaround I came up with is by using a mail queue plugin, the only one I found is: I tested it on WP 4.9.x and it works great. I have setup a custom cron job that runs every 5 minutes to process the queue, but you can make the interval faster like every 2 minutes. This way, users might have to wait a couple minutes before the mail arrives (because it is in a queue), but there is NO delay whatsoever on your site / store frontend. You can configure SMTP settings in this plugin so you can configure it for Office 365. This way you don’t need the CW SMTP add-on and you can setup per-site SMTP settings.


@contact9, thanks for the workaround! I have the same situation on another server (three sites) needing mail sent. When I get a chance I want to try this. The hardest part for me will be figuring out the cron job.


@lucash you’re welcome. The cronjob is easy to setup. You can also configure it without cronjob and it will run when WP cron runs, however, I prefer a custom cronjob because you will be sure it sends mails every X minutes (if there are mails in the queue). Configuring this on Cloudways is fairly easy, you can do it like this:

  • In the plugin go to Settings > SMTP Mailing Queue
  • Go to the tab ‘Advanced settings’ and check ‘Don’t use wp_cron’
  • Below this field, you will see a URL: call https://…?smqProcess… > you need this URL later for the cron
  • Now go to Cloudways and open your app in their portal. From the app management click ‘Cron Job Management’
  • Click the advanced tab and add the cronjob below on a new line:

*/3 * * * * wget -q -O - " https://www.the-url-from-the-plugin?smqPorcessQueue&key=XYXYX&t=date +\%s" > /dev/null 2>&1

That’s it. The 3 in this case means every 3 minutes. You can change it to */5 for every 5 minutes for example. Make sure to replace https://www.the-url-from-the-plugin?smqPorcessQueue&key=XYXYX with the URL that the plugin suggests. Also make sure there is no space between " http… so the cronjob should start like this: */3 * * * * wget -q -O - "http…

My example above contains a space but that’s because otherwise the editor here will format it as a quote.

How can I set Breeze not to cache data related to the mail queue?

I just started on Cloudways/DO two days ago and I’m wondering the the Cloudways SMTP addon works differently depending on the server vendor. I am using mailgun for SMTP. I did a test first with enabling the SMTP server addon (no wordpress smtp plugin) and tried sending email via a contact form. I tried twice and didn’t receive an email. I then turned off the SMTP addon and added the WP SMTP plugin and tried the contact form again. Then it worked and I got an email. The other two emails eventually arrived - one 20 minutes later, the other 80 minutes later. I figure for now I’ll use the plugin!
