Q1 All my e-mails are landing in the spam or junk box, how can I fix this?

Solution: Hi, it is not easy to work out why some e-mails land in the spam or junk box. You might like to read the following thread. This might help you.


Q2 I am using your plugin and I typed a wrong email address for testing purposes and it was accepted by your plugin and delivered. For example: Why is your plugin not blocking or preventing this?

Solution: Our plugin cannot check if SMTP actually delivers an email or not. It can only check if SMTP server accepted the email for delivery (which in this case, it did.). For example: A test email shows whether communication between your website and SMTP server can be established. Whatever happens to the email afterwards, cannot be tracked or handled by the plugin. Properly configured SMTP servers (not the plugin, but the server itself) should bounce undelivered emails back to the sender or to some pre-configured email. You can read more about it from the following forum post.


Q3 How can I add BCC to the settings.

Solution: Someone in the forum provided a solution. You can read more about it from the following forum post.

SPF Action Needed: It doesn’t look like the SPF record required by your SMTP server has been added to your domain. Please contact your SMTP server provider for details on how to find the SPF record, and how to add this record to your domain’s DNS.

Solution: When we’ve seen this issue before the issue is usually related to 1 of 3 reasons:

  • The new SPF records are still propagating. Sometimes propagation can take anywhere from 24-48 hours to complete.
  • There is a typo or some other form of error in the SPF record. Most website hosts will not allow duplicates, but please ensure that you only have 1 SPF record.
  • Your domain is registered on one website, but it is actually hosted on a different website. Please use to confirm the website host your domain is hosted on.

Q4 On October 1st Microsoft will be implementing a change to their mail service that will affect any mailboxes using older authentication. I don’t see anything in the settings for this plugin to modify the authentication type or any mention of this change in the support forum. How do I fix this issue?

Solution: As long as you’re using an App Password, you should be good. Basically, Microsoft made a change on their end that won’t allow you to connect with your normal password. Instead, you can create an App Password in your Microsoft account and use that. Check the following link forum post to learn more.

Amazon SES

Q1 I’m not able to send emails with this plugin using Amazon SES. It keeps returning this error:

CLIENT -> SERVER: [credentials hidden]CLIENT -> SERVER: [credentials hidden]SMTP ERROR: Password command failed: 535 Authentication Credentials Invalid
SMTP Error: Could not authenticate.CLIENT -> SERVER: QUIT
SMTP Error: Could not authenticate.

Solution: In order for it to work properly, you need to create your credentials in:

Amazon SES > SMTP Settings > Create SMTP Credentials button

If your credentials is created anywhere else it will not work – regardless if the user has the correct permissions or not. Check the following link forum post to learn more.
