Editing ActiveCampaign's deliverability guide to Gmail (section)

== Best Practices and Tips ==
- Establish a clean and engaged list of contacts by ensuring that users opt-in to receive communications.
- Always use a consistent '''From''' email address and encourage users to add it to their contact lists, as this improves deliverability.
- Make sure unsubscribe links are clear and easy to find to maintain a healthy mailing list.
- Avoid sending messages that could appear suspicious, such as phishing attempts or unsolicited emails, which will damage your sender reputation.
- Regularly clean and segment your contact lists to ensure you are communicating only with engaged recipients.
