I used this and it worked fine:
your10digitphone@txt.att.net
Found at Camera > Alerts, then under ‘Using the internet’ there is a setting named ‘Send an SMS text message to a cell phone’ click the ‘Configured’ button next to it, then add your cell phone number in the aforementioned format, for example, 123445566@txt.att.net
If you do this no email server etc are required, a SMS message will be sent to your phone.
Settings in detail
[Outgoing SMTP server] smtp.gmail.com
[port] 587 (when try port 465 it failed, this also prompted a warning from A/V program (Avast)
[Authenticate] check
Enter your full email address and password
[Sender] alerts@blueiris.com (you can put what you like here)
[Recipient] yourregualaddress@whatever.com
The rest I left on defaults as it should work fine with just the above, the rest of the setting are for further customization
Now you need to configure the SMS part, here are my settings.
[From email] yourphonenumber@txt.att.net – note, don’t use your email address here
[To phone #] your cell phone number – I included area code
[carrier] ATT
The rest I left on defaults as it should work fine with just the above, the rest of the setting are for further customization
I’ve just tried all of this out and it worked perfectly.
IT Vomit! 
Duplicate messages.
Ref, double emails – are you using a email client such as Outlook, or Hotmail etc?
I did not get duplicates using gmail.
It might be your email provider causing the issue, this may help you understand a possible cause.

Haven’t tried it, and I suspect it cannot be done, but there might be a way of sending a MMS message, but you are at he mercy of your cell phone carrier to help you out on that one.
Or, get a Smartphone or email capable cell phone, data account etc etc etc….more expense of course. You could ask friends if they have such devices and would help out with monitoring…just an idea. For my BI set-up, there are several members of my family who receive the alerts.
