Our emails being marked as SPAM. Please join Google Group!

We send email updates on any developments at DevgadMango.com, like start of accepting orders, dispatch of orders, etc. However, this giant called Google/Gmail has been marking them as SPAM, even though all emails are individually addressed. We regret many patrons missed our notification emails and also missed carrying home their orders.

We request our patrons to please join our Google Group so that you will not miss any notification from us. Please enter your email id in the Google Group registration form which you see on the right hand top of this blog just below where you see this image.                                                                                                                  
You would then get an email from Google with a link, asking you to confirm your intention to join the group. Please click on that link and you will get included in the group and not miss any notification from us.

Also, we send notifications on SMS, but they also get blocked. Those who have registered in the Do-Not-Disturb registry do not get SMS from us. However, we are surprised that we get many marketing SMS even though our numbers are also in the Do-Not-Disturb registry. Then why do the SMS we send get blocked? Can anyone help us on working around this? How do we ensure that our SMS reach our patrons?

UPDATE AFTER SUGGESTION FROM PAVAN
Request all our patrons to please check the SPAM folders for emails from us. If you find them, if you have not emptied the SPAM already, please mark our email as ‘not spam’. Thanks!
