Email sender guidelines FAQ
This FAQ provides additional, detailed information about our Email sender guidelines (previously called Bulk sender guidelines), which describe Google's requirements for sending email to personal Gmail accounts.
We update this FAQ periodically, so check back regularly to get the latest information and requirements for bulk email senders.
Important: Starting February 2024, Gmail will require the following for senders who send 5,000 or more messages a day to Gmail accounts: Authenticate outgoing email, avoid sending unwanted or unsolicited email, and make it easy for recipients to unsubscribe. Get the detailed requirements for sending 5,000 or more emails per day.
In February 2024, bulk senders who don’t meet sender requirements will start getting temporary errors (with error codes) on a small percentage of their non-compliant email traffic.
These temporary errors are meant to help senders identify email traffic that doesn’t meet our guidelines so that senders can resolve issues that result in non-compliance.

2.1. Bulk senders
What is a bulk sender?
A bulk sender is any email sender that sends close to 5,000 or more messages to personal Gmail accounts within a 24-hour period. Messages sent from the same primary domain count toward the 5,000 limit.
2.1.1. Sending domains:
When we calculate the 5,000-message limit, we count all messages sent from the same """primary domain""". For example, every day you send 2,500 messages from solarmora.com and 2,500 messages from promotions.solarmora.com to personal Gmail accounts. You’re considered a bulk sender because all 5,000 messages were sent from the same primary domain: solarmora.com. Learn about domain name basics.
Senders who meet the above criteria at least once are permanently considered bulk senders.
Does bulk sender status expire? Can I change my sending practices to remove my bulk sender status?
Bulk sender status doesn’t have an expiration date. Email senders that have been classified as bulk senders are permanently classified as such. Changes in email sending practices will not affect permanent bulk sender status once it’s assigned.
2.2. meeting the sender guidelines
How can bulk senders make sure they’re meeting the sender guidelines?
Bulk senders should use Postmaster Tools to check that their email practices are following our Email sender guidelines. To learn more, visit our Email sender requirements & Postmaster Tools FAQ.
2.3. Google Workspace accounts
Do the sender guidelines apply to messages sent to Google Workspace accounts?
The Email sender guidelines don’t apply to messages sent to Google Workspace accounts. Sender requirements and Google enforcement apply only when sending email to personal Gmail accounts.
When sender requirements aren't met What happens if senders don’t meet the requirements in the sender guidelines? To ensure messages are delivered as expected, bulk senders should comply with our Email sender guidelines. If senders don’t meet these requirements, messages might be rejected or delivered to recipients’ spam folders.
If messages fail DMARC authentication, can they be delivered using IP allow lists or spam bypass lists? Or will these messages be quarantined?
If messages fail DMARC because of authentication or alignment issues, the enforcement defined in the sending domain’s DMARC policy generally applies. If the sending domain doesn’t have a DMARC policy, the messages might be rejected or sent to spam.
Failing DMARC authentication is one of several factors that determine whether messages are rejected, sent to spam, or delivered as expected. DMARC authentication is an important determining factor, and so these messages are typically handled based on the enforcement setting in the sending domain’s DMARC policy.
