How to Ensure Spam Complaints Don’t Kill Your Deliverability in 2025
Written by Julia G
Spam complaints are signals of unwanted or unsolicited email communication. Typically they happen when a recipient marks an email message as “spam” or “junk” in their email client.
The most common situation when a recipient reports an email as spam is when they receive email communications they didn’t explicitly subscribe to. However, there are different reasons for subscription messages to be reported as spam, in particular:
the recipient finds email content irrelevant or intrusive;
the recipient can’t find an unsubscribe link;
the unsubscribe process doesn’t work;
the recipient is still receiving emails after they unsubscribed;
the company sends too many emails;
the recipient cannot recognize the sender.
