Cannot send email

Now I have no training in computers here. For Matter fact I have a degree in Hotel Management nothing to do with computers. however I do come on here from time to time to answer questions due to being an Apple user. Try and see if all your email account information is correct. Like for example did you enter all the right info when setting up your mail settings. I have accidentally entered one letter or number wrong and have gotten very frustrated and wanted to throw my computer across the room cause I could not figure out what the issue was only to find out that missed a number or letter or did not capitalize or entered the wrong letter in my name or email in the settings. Try to look that over. Or go in and take out your current email settings in your Apple email program on the current Apple OS and reenter the settings.

Hope I have helped and not made the situation worse

Best of luck

Both my iphone and ipad will not allow me to send any email. The written response after hitting the send button says” invalid sender address”. This began today. I am able to send email on the desktop, which is not an Apple product.

Was the sender address entered correctly... once I got the same message by typing name@gmail,com instead of name@gmail.com

How's it going?

Very strange, who is the Mail Provider?
