Very occasionally I need to know whether an important email sent on my IPad in Gmail has reached the recipient
Does anyone know how this can be done
It is only very occasionally as my use of emails is just personal as I am a retired person
It is not a matter of app features. Read receipt is a feature of the email protocol. Exchange has read receipt built in as a part of how it works. Gmail and other IMAP based services do not.
Well, you've piqued my interest - and agree w/ TP, i.e. a feature of the email client and settings that may be activated for 'read receipts' - for myself, I use a Yahoo account which does not offer this feature, likely true for many other clients - now, I continue to use my pre-retirement medical center account which is Outlook Exchange - first pic below shows that I could setup read responses, so even if an available feature, the user could still control the setting - interesting since I've never looked into option.
Now concerning Gmail which I do not use, there is not an option for 'read receipts' as already indicated - however, googling the issue brought up this hit Boomerang for Gmail (see 2nd pic below) - this appears to be a downloaded app (or extension - don't know) that can add the feature - this is only being offered as a possibility - I've never used and cannot vouch for this app/extension - checkout the link and proceed at your own risk? Good luck and let us know your results if you try 'Boomerang' - may be useful to others. Dave

It isn't a question of protocol (IMAP or POP) it is a question of whether the e-mail client, in your case the iPad e-mail app supports it, or if the e-mail service you are using (gmail) allows it.
There is no support on the iPad e-mail app for read-receipts.
Here is what Google says about gmail accounts and read-receipts:
Request or return a read receipt
To find out when people see an email message you send, request a read receipt. When the person opens your message, you'll get an email that shows the time and date of when it was opened.
Note: Request and return read receipts aren't supported in gmail.com accounts.
In the To and Cc fields, enter recipients as you normally would, and write your subject and message.
Read receipts aren't returned for messages you send to a group mailing list or alias.

Click Request read receipt.
You won't see this option with your current account [email protected]. Read receipts are available only if you use Gmail with your work or school.
By "work or school' it means that you have a Google Account that was set up through your work or school, a club, or maybe family or friends. This is often called a G Suite account. If you also have another Google Account that you set up just for yourself, you might notice some differences when using each account.
