It is clear that the main objective of your email marketing strategy is that your mailings reach your subscribers' inboxes without any problems. As we discussed in "My subscribers are not receiving my mailings" anti spam filters can be difficult to predict, but even so there are some guidelines to follow if you want to avoid your campaigns end up in the spam folder.
Each email client has its own criteria for what is spam and what is not, but there are some common criteria that we can follow to avoid compromising the deliverability of our campaigns. Here are some basic guidelines and best practices to ensure that your mailing gets past spam filters:
Pay special attention to respect the will of your subscribers and never send to contacts for whom you do not have explicit consent. In addition to having a serious legal problem, if many users mark your campaign as SPAM, it is possible that the mail servers will end up blocking your mailings to all recipients.
