In 2024, Google and Yahoo implemented stricter requirements for bulk senders. If you send more than 5,000 emails a day, you must authenticate your emails and maintain a low spam rate. Here is your survival guide.
You must set up SPF, DKIM, and DMARC. These protocols verify that you are who you say you are. Without them, your emails are likely to be rejected.
Google now requires a spam rate below 0.3%. This means for every 1,000 emails, no more than 3 people should mark it as spam. Relevant content is key.
Sending to invalid addresses is a huge red flag. It tells ISPs that you are buying lists or not maintaining your data. Use a tool like Kaiju to remove hard bounces before you hit send.
