How to avoid spam complaints
What are spam complaints?
Spam complaints occur when a recipient reports your email as spam. Receiving a large number of spam complaints can be detrimental to your sender reputation. Having a damaged sender reputation may result in your emails being delivered directly to the spam folder and affect your overall email deliverability.
What happens if a recipient reports an email as spam?
If your recipient's email provider supports feedback loops, MailerSend will be notified of this, and the spam complaint will be reported in your MailerSend analytics.
MailerSend will also automatically move recipients who report your emails as spam to your spam complaints suppression list.
3 tips to avoid spam complaints
To maintain a healthy sender reputation, you must employ these best practices to avoid spam complaints:
1. Practice legitimate email collection methods
If you’re sending marketing emails, you should only add consenting recipients to your mailing list.
Keep in mind that consent expires.
Marketing permission from a recipient lasts for up to 2 years. If you have not contacted that recipient within that time frame, you no longer have the right to do so.
2. Use a recognizable sender address
Always use a sender address that matches your domain name. If a recipient doesn’t recognize you as a sender, they’re more likely to mark your email as spam.
3. Protect your webforms from abuse
Spambots (computer programs designed to carry out repetitive tasks) attack your unprotected webforms by submitting multiple email addresses to your form.
In most cases these email addresses are invalid, which will lead to an influx of hard bounces—But in some cases, spambots will submit purchased lists to your webform that might contain real, valid email addresses. When you then email these recipients, you are sure to see a large number of spam complaints in your analytics.
To prevent spambots from successfully submitting email addresses to your signup forms, you can use one (or more) of the following tactics:
Enable double opt-in on marketing signup forms
Enable reCAPTCHA on your webforms
Include a hidden “honeypot” field on your webforms that only spambots will see and fill out (recipients who enter a value into the honeypot field can then be disregarded)
