How to avoid being spam?

Maillist Controller (Mailing list controller) sends mail messages in the same format as your e-mail client. The format of information, the encoding of information, or the mailing process itself is not a problem. Most of the time, the content of the information is considered to be http://www.aliyun.com/zixun/aggregation/12915.html "> spam" reasons. Check your message content and topic:

1, avoid typical spam phrases, such as: Business Offer

2, when sending HTML message contains plain text part (!)

3, avoid inline pictures with text

Check your e-mail address list and mailserver list. (SMTP server)

1, make sure the email address list is included in the outgoing mail server (SMTP)!

This is very important. If the email list comes from a different provider, you will be blocked by most anti-spam filters and the message will be rejected by the mailserver.

2, now, many mailserver support the transmitter Policy framework (SPF), as defined in RFC 4408, or use DomainKeys identified mail (domain name keyword authentication message, DKIM) to combine domain names with e-mail.

It is recommended to send a test message to a spam-protected e-mail account, or to a webmail account (for example: Freemail), to verify the spam level of the information.

Send e-mail messages to subscribers and allow them to unsubscribe.
