Sending email on behalf of another user

Question

In my system there's an option for a user A to send an email reminder to user B. When choosing this option, user A gets the following form:

In an ideal solution, the email sent to user B will look like sent from user A, however this is email spoofing, and it's not something I would like to do.

Is there a best practice for an email template / text that will make it clear that was originated from another user and is not an automatic email?

Answer 1

LinkedIn messages sent from a person to another person could be a good example for such web app messages.

They are being sent by a person, but the sender appears as "[email protected]". The subject is a regular subject (no "via LinkedIn" or anything)

Here is how some of the relevant fields in the sent email look like:

• from: UserA via LinkedIn

• reply-to: [email protected]

• mailed-by: bounce.linkedin.com

• signed-by: linkedin.com`

Answer 2

Businesses do this all the time, staff is in constant communication.

EXAMPLE: Buyer makes a Purchase Order and sends note to inventory to verify existing inventory (sometimes there is a difference between what's noted in the system and what actually exists).

Make it clear in the subject line and email address that this is happening (as well as in the body of the email. If this is not for an intranet but is more distributed then, of course, the user should have to opt in.

In any case the posts must be clearly shown that it came via a web form.

EDIT (As for example)

Subject: [Via App X] "Subject entered by user"

FROM: [Via App X] [email protected]

The recipient needs to know (perhaps it's good branding as well) where, and from who, the email came from.
