Question

Sent out sms and for some reason not everyone received it, if / what’s the best way to see who did not receive it?

Answer 1

To understand the answer you must know how SMS sent gets to the persons Cell Phone. Please read the explanation carefully.

 

Almost every carrier (Except Google Voice) has an email gateway where you can send in a text message to one of their subscribers. Which means that you can send an email to that gateway (91700000000@CellGateway.com) and they will forward it to the cell phone. So after we detect which carrier this cell phone number has we tell your email provider that you setup to send an email to the correct gateway.

Now because of the problem of SPAM email and text all companies has some mechanism to block emails that they think is not wanted by the receiver.

So your email can be blocked in a few places. First your email provider might refuse to send it out because its above a quota or it doesn't look good to them. In this case some times they will respond with a message to our software that they are not sending the email. This message will be displayed an an error message when sending the email with the text that your email provider sent why they are not sending it. (For example: 50.0.09 Quota Exceeded).

Other time your email company will accept the message but never send it to the carrier because it was blocked after they accepted it from us.

Now even if your email provider is sending the message on your behalf to the carrier, the carrier might block it for various reasons. They have limits how many emails they accept from same email etc etc. Each carrier has different rules. In this case even your email provider does not know that its never sent to the cell phone as the carrier accepts the message and just ignores it.

So all we do is ask your email company to send the email to the carrier. Whatever happens after that is simply not in our hands at all and we have know way of knowing.

There are companies out there that have a better deliver-ability record. They throttle and try to make sure that your message gets thru. If you send less than 25,000 sms/email per month you can have them send your email for free. We discussed the option here (https://jlssolutions.com/QA/2814/schedule-specific-getting-messages-emails-havent-arrived)

So if you did not get an error message we sent it to your email provider successfully.

You can have A BCC email setup in admin and there you can see what was last sent. Or if you use GMail you can check your sent folder.
