If you are on a device that is not a phone, you can send something to a text recipient if you know their cellular carrier. For example, my granddaughter doesn’t read her email account very often, but she reads her text instantly. I use my iPad or laptop a lot, and sometimes want to send her something from my Gmail account. I can use this method now, it works well.
All you have to do is use this “text address” as the address in your email: “10 digit phone” @ “carrier address” without the quotes. For example, suppose you have a Verizon phone number of 123-456-7890, you would send your message to 1234567890@vtext.com
Some carrier addresses are:
T-Mobile: tmomail.net
MetroPCS: mymetropcs.com (now owned by T-Mobile)
Google FI: msg.fi.google.com
Verizon: vtext.com
AT&T: txt.att.net
Virgin Mobile: vmobl.com
If you don’t know someone’s carrier info, get them to send a text to your email address. This would give you their texting “email” address.
Note: The above is for SMS texts. If MMS systems, the carrier address may be different.
BTW, just add these secondary “text addresses” into your contact lists to make it simple to send.
