Sender Requirements Checker

Check if your domain meets Google and Yahoo's 2024 email sender requirements. Essential for bulk senders (5,000+ emails/day).

New Requirements Since February 2024

Google and Yahoo now require email authentication (SPF, DKIM, DMARC) for all senders. Bulk senders must also implement one-click unsubscribe and maintain low spam rates.
