Check out Pure360 – from their website it seems like they have both SMS services and integration with Salesforce. I can’t vouch for their service as I’ve never used it, although I did used to live about two minutes from their offices in Brighton! The other option would be something like Infusionsoft. I’m pretty certain that they have SMS functionality, and would be very surprised if they didn’t integrate with Salesforce.

Keep the subject line and pre-header short: The subject line is crucial. Keep it short so the reader knows exactly what the email topic is about. And the pre-header text (also known as snippet text), don’t let it go to waste by using “To view this email in your browser…”. Instead, summarize the email or include a call to action (i.e., Use “FREESHIP” to get free shipping).
