Email complaint handling

How eMarketeer handles email complaints and what you can do to minimize them.

Complaints affect deliverability and sender reputation. Understanding how they are handled helps you protect both.

What it means

Some email service providers (ESPs) let recipients report marketing emails as spam or unwanted. When a recipient does this, the ESP sends a complaint report back to the sending platform.

eMarketeer automatically receives complaint reports from ESPs that support this functionality. When a complaint is received, the affected contact is automatically unsubscribed from future mailings.

Why it matters

• High complaint rates negatively affect email deliverability.
• Repeated complaints damage your sender reputation with mailbox providers.
• If complaint rates become too high, email sending may be temporarily or permanently blocked for your account, meaning no emails can be sent.

Automatic complaint handling protects both you and eMarketeer, but it cannot compensate for poor sending practices.

What you should do

To minimize complaints and avoid sending restrictions, follow email marketing best practices:

• Send only to recipients who have explicitly opted in.
• Make unsubscribe links easy to find and use.
• Keep content relevant, expected, and consistent.
• Avoid sudden or large increases in sending volume.
• Clearly identify yourself as the sender.
