Email Marketing: Permission, List Hygiene and Useful Campaigns
Build campaigns around consent, relevant audience groups and clear measurement—not bought lists or misleading subject lines.
Build a list with clear permission
Explain what subscribers will receive when they sign up and collect only the information you need. Do not assume that purchasing a list gives permission to send marketing. Follow applicable privacy and electronic-communications requirements for your audience.
Send relevant messages
Group subscribers using information they provided or interactions they expect you to use. Match the subject line and message to the offer, identify your business clearly and include a working way to unsubscribe.
Maintain list quality and privacy
Remove invalid addresses, respect opt-outs and limit access to subscriber data. Avoid collecting sensitive details without a clear need and suitable safeguards. Keep records of how and when people joined where your process requires it.
Measure outcomes responsibly
Track actions that match the campaign goal, such as visits, enquiries or purchases. Email opens can be affected by privacy features and should not be treated as a complete measure of human engagement. Use testing to improve usefulness and clarity, not to obscure the offer.
Frequently asked questions
Can I use a purchased email list?
A purchased list may not provide the permission or expectations required for sending marketing. Check applicable laws and your email provider’s terms; in general, build a list through clear, direct sign-ups.
What should every marketing email include?
Use a recognisable sender, an honest subject line, relevant content and a clear unsubscribe method. Include any disclosures or contact information required by applicable rules.
