Technical Setup: Properly setting up SPF, DKIM, and DMARC is crucial. These authentication protocols are like an entrance ticket to the email deliverability "nightclub."
Engagement: Sending relevant and engaging content is vital. Gone are the days of broad, untargeted email blasts.
Testing and Monitoring: Regularly test your emails by sending to various free email accounts and use tools to check your inbox placement.
Double Opt-In: While not legally required in the U.S., using a double opt-in process can significantly improve your deliverability by ensuring recipients engage with your first email.
