Within Teamwork Desk, there are limits in place to improve deliverability and prevent misuse of the email service that could result in being blocked.

Receiving email


For all accounts, the limit is:

  • Daily limit of 16,000 messages
  • Hourly limit of 4,000 messages
  • Ten-minutely limit of 150 messages
When this limit is reached emails will be temporarily blocked and email delivery will be delayed. After 8 hours it is considered permanently failed.


Sending email


For all verified domains there is a daily limit of 4,000 messages.

For all unverified domain there is a limit of 25 tickets per day.

Your domain is considered unverified until the following are met:

  1. You have validated your domain via DNS CNAME records.
  2. You have a paid subscription and have a valid credit card on file.

If you would like to request an increase in tickets allowed per day, please contact us at support@teamwork.com to discuss your options.

Tickets and attachments


  • Characters: Each reply on a ticket is limited to a total of 1,038,336 characters.
    • Quoted content included in a reply counts towards the character limit.
    • When a reply exceeds the limit, you will be given an option to send the reply without the quoted content.
  • Content: Each reply or note is limited to a total content size of 5MB.
  • Attachments: Each reply has a 20MB total size limit for attachments.
    • This same limit also applies when merging tickets into a single ticket thread.
    • Most file types are supported in ticket attachments as long as they fall within the 20MB limit.
    • Attachments from previous messages in the ticket will be added as links into the body of the message. These files will be available for download by anyone with the link and expire after 30 days.


Storage space


There are no limits on storage space.

The Teamwork Desk API is limited to 120 requests per minute. If this limit is reached Desk will respond with 429 Too Many Requests.

Desk will also set the X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset headers, so you can check how many remaining requests you have.
