Did your open rate recently plummet? The answer is only five letters: DMARC. Beginning 2024, you must enable DMARC. To Enable DMARC: Add a TXT record to your DNS with a host of: _dmarc.yourdomain.com and a value of: v=DMARC1; p=none Pick your desired TTL and save the record.  You can use this website to check if DMARC has been enabled for your sending domain. It can take anywhere from 24-48 hours for the TXT record creation to go into effect. Copyright © 2024 Timothy Spaeth
