The basic hosting plan has an email size limit of 5MB that can be sent or received.
If you need to send files larger than 5MB, you can upload the files to your Doteasy FTP & simply send the URL for the file which the recipient can visit to download the file.
Alternatively, you can consider upgrading to either our Ultra or Unlimited hosting plans which provide an email size limit of 10MB.
You can also purchase the Doteasy MailPro add on service which will increase your email message size limit to 20MB
