Do your emails often end up in your recipients’ junk mail? Email deliverability is not an exact science, as it depends on many factors. It is important to note that the criteria for spam categorization vary depending on Internet Service Providers (ISPs) and email clients. In this article, we will explain how to know whether your emails are classified as spam, the most frequent reasons behind this classification, and how you can reduce the risk of ending up in spam.
Abnormally low open and click rates may be a sign that your emails are being filtered as spam or are being filtered upstream by the servers.
Non-delivery or rejection messages may indicate that your emails are being filtered even before reaching your recipients’ inboxes.
Send your emails to test addresses to check whether they arrive in the inbox, in the spam folder, or do not arrive at all (and are therefore filtered upstream).
Content including words frequently associated with spam (also known as spamwords), suspicious links, or poorly formatted content may trigger alerts from spam filters.
The use of non-opt-in email lists or sending to recipients who have not consented to receive your emails may result in being classified as spam.
If your IP address or domain is associated with past spam sending, this may affect the deliverability of your emails
ISPs often consider emails without interaction (opening, click, reply) as suspicious.
Configuration errors of the sending server or domain validation issues may also impact the classification of your emails.
Obtain the explicit consent of recipients and allow them to manage their subscriptions.
Write relevant, well-structured emails that are free of suspicious terms.
Avoid sending dubious attachments or executable files.
Implement these protocols to strengthen the authenticity of your emails.
Use monitoring tools to track the reputation of your IP address and your domain.
Do not hide the unsubscribe option, do not purchase email lists and, in general, do not use techniques associated with spamming.
Send targeted emails based on the recipients' interests.
By following these recommendations, you will increase your chances of delivering your emails directly to your recipients' inboxes, rather than having them filtered at the beginning of the delivery chain or ending up in the spam folder.
