Hey lemlister, let's work together to maintaining the best sending practices and email deliverability possible!

Sending guidelines

To reduce the chances that messages from your domain are sent to spam or blocked by Gmail, follow these general best practices.

Recommended sending practices

  • Authenticate email with SPF and DKIM that are aligned. If you use an email provider, verify that your provider supports this.

    Relevant information mentioned in the articles tagged below:

  • Ideally, send all messages from the same IP address. If you must send from multiple IP addresses, use a different IP address for each type of message. For example, use one IP address for sending account notifications and a different IP address for sending promotional messages.

  • Messages of the same category should have the same From: email address. For example, messages from a domain called might have From: addresses like:

  • Messages sent from an address in the recipient’s contacts are less likely to be marked as spam.

Sending practices to avoid

  • Don't mix different types of content in the same message. For example, don't include promotions in sales receipt messages.

  • Don't impersonate other domains or senders without permission. This practice is called spoofing, and Gmail may mark these messages as spam.

  • Don't mark internal messages as spam. This can negatively affect your domain's reputation, and future messages might be marked as spam.

  • Don't purchase email addresses from other companies.

  • Don't send messages to people who didn't sign up to get messages from you. These recipients might mark your messages as spam, and future messages to these recipients will be marked as spam.

  • Avoid opt-in forms that are checked by default and that automatically subscribe users. Some countries and regions restrict automatic opt-in. Before you opt-in users automatically, check the laws in your region.

Some legitimate messages may be marked as spam. Recipients can mark valid messages as not spam, so future messages from the sender should be delivered to their inbox.

Remember that while following these practices reduces the likelihood of your messages being marked as spam, some legitimate messages may still face this issue. Recipients can mark valid messages as not spam, helping future messages reach their inbox.
