Preventing your campaigns from being marked as spam

If you maintain a clean list with subscribers who have opted-in to receive your newsletter, you do not usually have to worry about your email marketing efforts being marked as spam. There are different factors that determine whether your campaigns end up in the spam folders of your recipient's email service: 

Sender reputation

A recipient's email client (for example, Gmail, Outlook, and so on) reviews the sender address of your campaign before deciding whether to accept or reject the email message. Therefore, you must set up SPF and DKIM frameworks. These frameworks boost your sending reputation by letting the recipient's email client know that you are sending your campaigns using Moosend servers.

Message content

When your recipient's email client examines your newsletter, the content is analyzed to determine where your messages go. To make sure the newsletter goes to the inbox and not the spam folder, make your content relevant to what your subscribers expect, and use the content analyzer to test the newsletter's content

Delivery failure

If your newsletter cannot be delivered, it is considered as spam. A delivery failure is called a bounce. There are two kinds of bounces: a soft bounce and a hard bounce.

High bounce rates affect your sender reputation and prevent you from achieving higher email delivery rates. You can reduce the number of bounces by implementing some key email deliverability best practices:

  • Keep your mailing list clean - clean your list regularly and delete non-responders and invalid addresses.
  • Use double opt-in - Have users confirm their email address to avoid having invalid recipients.
  • Monitor email message delivery - Pay close attention to bounce rates as well as response rates to avoid potential damage before it happens.
