Sender reputation
Maintaining a good sender reputation is key to ensuring reliable delivery. Bad sender reputation reflects negatively on you as a sender, and us as a provider.
Sendamatic provides feedback and tools to help you keep your reputation high, and take action on any problematic recipients.
Excessive bounces, complaints, or poor sending practices put your account at risk of suspension.
Tips to maintain a good reputation
-
Never buy, rent, or share email addresses. Only send to addresses that specifically requested your mail.
-
Use double opt-in - send a confirmation email that the user needs to click before they receive any additional mail.
-
Be careful not to encourage people to use fake addresses - for example, don't offer any additional features until an email address has been verified.
-
Ask users to enter their email addresses twice, and ensure the addresses match. Consider using a CAPTCHA or similar method to help prevent automated submissions.
-
Be clear about the type of email users will receive, and only ever send the type of mail that they signed up for.
-
Ensure that your mail is well-formatted, professional, and is clearly from you.
-
Consider monitoring user engagement - stop sending to recipients who don't interact with your messages.
-
Give users a clear and easy way to unsubscribe from emails, and process the requests promptly.
-
Immediately remove bounced email addresses from your list.
Spam traps
Email spam traps serve as decoy email addresses to attract and analyze unwanted spam messages to improve spam detection and filtering for all users. They don't belong to real users. Types of spam trap include:
Recycled traps
If an address or domain has been inactive for a period of time, it may be brought back into service as a spam trap. Hits to this sort of trap can indicate poor list hygiene or bad bounce processing.
Pristine or pure traps
Some spam traps use email addresses that have never been active. Hits to these traps suggest that addresses have been acquired from web scraping, dictionary attacks, or purchased lists.
Typo traps
Repeated attempts to send to common domain typos, for example hotmal.com or gmial.com, suggest poor address collection practices and a lack of double opt-in process.
