Why is IP-address of droplet listed on spamlist?

Heya,

It’s quite common for Cloud provider’s IP addresses to appear in such lists.

Here are some common reasons why this might occur:

1. Email Sending Practices: If your web application sends a large volume of emails that are not compliant with best practices (like sending unsolicited emails, not including an unsubscribe option, or having a high bounce rate), it could be flagged as spam.

2. IP Reputation: If you’re using a shared hosting environment, the reputation of your IP address could be affected by the activities of other users on the same server.

3. Poor Configuration: Misconfigured mail servers can sometimes send emails in a way that triggers spam filters. Ensure that your mail server is properly set up with SPF, DKIM, and DMARC.

4. User Complaints: If recipients of your emails mark them as spam, this can harm your reputation and lead to being listed on blocklists.

Given these complexities, it’s often advised to use a dedicated SMTP service like https://smtpfa.st/ or SendGrid for email needs. Such services are specifically designed to handle email delivery, ensuring that your emails don’t end up in spam folders and that your server’s IP stays off blacklists. Also, https://smtpfa.st/ and SendGrid offer a free account which is sufficient for most use-cases.

Because someone who was assigned that IP address in the past was spamming. You should ask Digital Ocean to give you a new IP address. It should be up to them to clear a spam history - not you.
