Compliance with data protection regulations and building trust are essential for a successful email list:
Adhere to GDPR and CAN-SPAM regulations to ensure you’re collecting and handling email addresses legally. Include a clear privacy policy on your sign-up forms explaining how you will use the subscribers' information. Use a double opt-in process to confirm that subscribers genuinely want to receive your emails. Provide an easy and visible unsubscribe option in every email you send.
