To keep our systems healthy and combat spam, email providers limit the number of mails each user can send. These limits restrict the number of messages sent per day and the number of recipients per message. So you will encounter an error when you send emails from Freshworks CRM using your email provider's SMTP server.

For example, say the maximum limit for the number of mails is 1000 per day and if you attempt to send more, an error message pops up. 

Sending limits can change without notice. Limits per day are applied over a 24-hour period, not any specific time of the day.

Each provider has a different limitation. You can find the limits for the most used email providers below:

Gmail

After reaching one of the below limits, a user can't send new messages for up to 24 hours. However, they can still receive incoming email. After this suspension period, sending limits are automatically reset and the user can resume sending mail.

These are the major limitations set by Gmail:

Office 365

LIMIT TYPE

LIMIT


Incoming & Outgoing message rate


30 messages per minute, 10,000 messages per day


Recipients


500 per message

Note:
1. Refer respective support articles to know the daily limits for other email providers.
2. To avoid exceeding limits while sending bulk mails, like in case of email campaigns, send to one group of recipients, wait for 24 hours and then target another group.
