Message Length: Emails can be lengthy and can share detailed information in one-go. Unlike SMS, which only has 160 characters in a message so it can only share short and concise messages to the audience.

Read rate: Emails are generally read within 90 minutes after they are sent. On the other hand, text messages are read within 3 minutes with a 98% open rate.

Format of the message: Unlike SMS, Emails have a subject line to give an insight on what to expect from the mail, attached images, and more than one call to action can be shared in the mail.

Delivery: SMS can be delivered without access to the internet and Email requires the internet to deliver information to the audience.
