We recently released an article about the major differences between SMS messages and MMS messages. In keeping with the same theme of defining terminology of text message marketing, this post will touch on the major differences between 2 types of delivery for text messages: true SMS (SMPP) vs SMTP. Both are protocols used in defining how a text message is delivered.
What is the SMTP Protocol?
“SMTP” stands for simple mail transport protocol and is the protocol used when sending email. It was first developed in 1992 as the method of delivery for email messages and is still used today for the same purpose. The wireless carriers have provided the ability for each cell phone to have an associated email address with it in the format of:

For example, an AT&T customer could use SMTP to send an email to their phone as a text message, email to SMS, by sending it to:

What is True SMS (The SMPP Protocol)?
The SMPP protocol is the “true SMS” protocol and is developed by the telecommunications industry specifically for transmitting SMS messages. “SMPP” stands for short message peer-to-peer protocol and is the protocol used whenever a text message is sent from a mobile phone to another mobile phone. SMPP has numerous advantages, in comparison to SMTP, when using it as a method for mobile marketing.
Disadvantages of SMTP Protocol
While there may be an appeal to using the SMTP vs SMS protocol as the transport for text messages, there are several disadvantages that make it not-so-glamorous. While it is true that the only costs involved with SMTP is bandwidth and the time taken to update the carriers’ domains periodically, the disadvantages outweigh the costs. The disadvantages of SMTP are as follows:
When comparing SMS versus SMTP and selecting a text message provider, it would be in your best interest to choose a provider that offers the true SMS protocol as their delivery method. It will save headaches in the long run if you don’t have to worry about all the disadvantages of SMTP.
