IP reputation refers to the perceived trustworthiness of an IP address when sending emails or other online communications. It's based on various factors, such as:
The volume of messages sent
The number of spam complaints received
The quality of the recipient engagement, etc.
Even though we monitor the IP addresses of all VPS with the help of the largest reputation providers, your IP may still get reported to any of the existing blacklists, which would prevent you from sending emails.
Our VPS service is designed for regular business email operations: the sending limit is five emails per minute. If you need to send more messages, for instance, if there's an email marketing strategy you want to follow, you should use a dedicated email service, such as Business Email.
If the IP of your VPS is blacklisted, first, ensure you implement the following email practices:
Avoid sending large volumes of messages, especially to recipients who haven't explicitly opted in to receive them
Keep your message subject and content targeted and informative
Make it easy to opt out of your communications
Remove inactive or non-existent recipients from your contacts
Use SPF, DKIM, and DMARC records to verify your identity and improve the deliverability of your messages
Next, locate the service that has blacklisted your IP address, and submit a delisting request. The process varies according to the reputation provider.
Some providers may list the IP due to missing or incorrect mail server configuration. It's highly recommended to review the documentation and FAQ articles for these blocklist providers and take initial action based on their recommendations. We suggest you:
Configure a valid hostname
Set up a PTR record for your IP address
Review and adjust your mail server configurations
