Emails promoting affiliate offers often get blocked when senders don’t follow proper email practices. One common reason is using a sender name or email address that looks suspicious or doesn’t match the domain. Email providers see this as a red flag. Also, using spammy subject lines or including too many sales links can trigger filters. Another issue is sending emails to a list that has many inactive or fake addresses. If too many people mark the emails as spam or don’t engage with them, your reputation as a sender drops, and your emails may stop reaching inboxes.
Sending bulk emails too fast without warming up your domain also leads to problems. Affiliate marketers who don’t set up authentication like SPF, DKIM, and DMARC may also face blocks. These settings help prove your emails are safe.
