Tofield for a mail shot.
To avoid misuse and optimize the deliverability of e-mails sent by its servers, alwaysdata has always implemented a scoring system based on various criteria like the content and frequency of the messages sent.
The lower the score, the better the e-mail will be rated and the sending accepted. In shared servers, any e-mail with a score higher than 3 will be blocked. In VPS and dedicated servers, the default value is 5 and you can change it in the SMTP > Settings tab of your server.
Based on this scoring, the message will be sent via an IP address with a more or less good reputation. This way, by optimizing the quality of your e-mails and their content, you will have a better chance of avoiding your message being considered undesirable.
This system uses SpamAssassin. Depending on its score, it will trigger one of our anti-spam rules:
+1SpamAssassin score: medium => SpamAssassin’s score is between 0 and 3;
+2SpamAssassin score: high => SpamAssassin score is between 3 and 8;
+3SpamAssassin score: very high => SpamAssassin score is higher than 8.
And a set of rules specific to his system :
+1: Mass e-mails: the account has sent more than 15 e-mails in the last 30 minutes,
+1: Customer is restricted,
+1: New customer: the profile was created less than 30 days ago,
+X: Too many bounces (in percentile): the number of e-mails sent back with an error. This is updated every three hours. If the number exceeds 10%, the system will add
+1point and if it exceeds 30%,
In order not to be dependent on abuse from other clients using the same mail server you can rent a dedicated IP in the Advanced > IP Addresses tab of the account. You can finally configure for which notes given by the antispam, the e-mails will be sent by this IP.
