There are daily send limits for both one-to-one emails and sequences emails sent from your connected email accounts in HubSpot. HubSpot will alert you when you're close to hitting either send limit. These limits apply to a rolling 24-hour period and do not reset at a specific time of day.
|HubSpot send limit
|A daily send limit on one-to-one emails sent from an inbox connected to HubSpot. This limit applies to emails sent from a personal inbox or from a team email address connected to the conversations tool.
|Sequences daily send limit
|A daily send limit on automated emails sent via sequences. This includes any sequences emails that are scheduled to send from previous or new sequence enrollments and paused sequence enrollments. Your send limit varies depending on your HubSpot subscription.
Each email provider has its own rate limits on the number of emails you can send each day. Limits for inboxes connected with Exchange or IMAP vary depending on your mail client; learn more about rate limits for Gmail and Office 365.
A provider's rate limit sometimes include additional limits, such as a bandwidth limit. Therefore, it's possible that you could reach your provider's limit even if you haven't exceeded the number of allotted email sends.
Please note: connecting the same Office 365 account multiple times to a HubSpot account can cause you to quickly hit the rate limit error. It is recommended to connect the Office 365 email address to a single user's account.
There is a daily send limit on one-to-one emails sent from a connected inbox. This daily send limit applies to emails sent from a personal inbox or a team inbox. These limits prevent you from exceeding your email provider's send rate limit. HubSpot send limits vary based on each email provider's limit:
Due to limitations in Microsoft's Graph API, each email sent from a connected Microsoft Outlook inbox is subject to a maximum size limit of 4 MB. To avoid exceeding this limit, you can reduce the size of your emails by trimming out extraneous
characters in the body of your emails, and minimize the number of emails in a single thread.
If you connected a team inbox to HubSpot, any message sent from the conversations inbox or from a CRM record has a limit of 50 total recipients, which includes any combination of addresses specified in the To, CC, and BCC fields of the email.
If you're a user with an assigned Sales Hub Professional or Enterprise or Service Hub Professional or Enterprise seat, you also have a daily send limit for emails sent in sequences. You can review your send limit in HubSpot's Product & Services Catalog.
The sequences send limit is based on the number of sequences email sends on a given day, not the number of new enrollments. The limit includes all emails sent immediately when a contact is newly enrolled in a sequence and any scheduled sends from previous enrollments. For example, if your sequences daily send limit is 500 and you already have 450 emails scheduled to send on a given day, you can only schedule an additional 50 sequences email sends that day.
HubSpot will notify you if you try to start a sequence with emails to send on a day when the limit has been reached.
To enroll contacts in sequences, you'll need to update the date of the email send.
