To prevent your domain / email address from being labeled a 'spammer', you will need to ensure that the recipients have given their affirmative consent to receiving email from you, with something like the double opt-in method.
It is also important that you have clear methods in place that allow the recipient to easily revoke their consent i.e. an ‘unsubscribe’ or ‘remove’ link in the mail (normally in the footer).
Best Practices for managing an authentic mailing list
- Use a double opt-in method. Not only must the user take action to add their email address to a list, but they receive a confirmation email of their subscription. The user must reply to the email to be added to the list. This is done to ensure that the user did not subscribe by mistake or that another person did not subscribe their email address.
- A ‘remove’ or ‘unsubscribe’ link (an opt-out method) must be provided to make it easier for the recipient to revoke consent or to cancel their subscription. Emails must cease immediately once the subscription is cancelled.
- Mailing list administrators must take adequate steps to ensure that their lists are not used for abusive purposes.
- Avoid multiple font sizes and colours as these promote mail being flagged as spam.
- Blank spaces increase your spam percentage allocated by most scoring systems.
