When you use an SMTP client like Gmail, Outlook, or any other email client to send messages, you can set up the message’s subject to be the sender’s email address.
But if you’re using a different email client, the subject is the recipient’s email.
That means if the sender and recipient have different email addresses, they’ll never see each other’s messages.
In Gmail, for example, you’ll see your message subject as “from” but it will be sent to someone who’s a different Gmail address.
It’s an annoying problem, especially when you need to make sure your messages are always visible to both sender and receiver.
This is especially important if you’ve got multiple accounts, because your recipients may be receiving messages that have the subject sms-send-message.
When you’re dealing with multiple accounts and you’re receiving messages from multiple users, you need some way to separate those messages from the sender.
One common solution is to create a private SMTP address, which is a unique domain name.
The problem with creating a private address is that it’s a bit complicated to remember, and you can’t easily add a domain name to an existing domain.
If you want to set up a domain, you’d better have the domain name in the first place.
That’s why we’ve got a handy guide to the basics of using domain names for your SMTP addresses.
In the meantime, we’ve covered the basics here.
If your email client doesn’t support domain names, you might want to look into adding domain names to your smtp messages.
