Adding attachments to your emails or SMS can be of great help to your business, especially by doing it quickly from the Conversation channel and by not having to worry about the file size. In this article, you will learn how to upload large files directly from your devices.

Adding the file

  • Go to Conversations and search for the contact that you want to send the file to

  • You can drag and drop the file in the conversation or attach it with the clip icon

  • Your phone number should be MMS enabled to send attachments in an SMS. We support up to 10 attachments, as long as the total size of the message body text and all attachments is less than 5 MB.

Notes: 

  • Users can now upload large-sized attachments directly from their devices or if you prefer from the media library

  • All files in SMS and any exceeding the email attachment limit (25MB) will be automatically uploaded to the media library.

  • These attachments will be added directly as media library links.


Moe Ameen is a real estate investor, software creator, and general over-caffeinated human who somehow made automation cool (or at least tolerable). He built a cutting-edge real estate CRM because manually chasing leads is so last century. Specializing in creative finance, deal structuring, and making things unnecessarily efficient, he helps investors close more deals while doing less actual work. When he's not automating the real estate world, he’s probably pretending to work while staring at spreadsheets or convincing himself that buying another domain name is a good idea.
