Without an option to have verification that an email was received I am unable to use this as a primary email service for any business related messages.

I used to have bigstring and it was a super innovator it allowed you to view how many times a person viewed a mail and gave you a time option. I could send a final with a few seconds to self-distruct option without a trace. I can't tell you enough how this is important in my line of communication. You can determine honesty in this manner. I need people who know what's right from what's wrong without any vacilation. I have dealt with time critical matters that not only cost people money but in some cases in war torn places their very lives.

mail receipt and read prove of delivery

Love it....

I would rather prefer to have this option developed by PM team than allow 3rd party to scan my emails, and most of them are on US soil anyway

Read receipts are notoriously unreliable, as there is no standard for them. They often only work for users on the same service and with compatible mail clients.

Many users also disable them for privacy reasons.

If ProtonMail implemented this it would not work correctly with any external address, and the vast majority of ProtonMail users would disable it.

I know I'm not the first one to request that feature, but it's been requested in 2016, and is not available yet... (!).

Do you know there are times you NEED that feature for very important messages ?

Thank you.

Me too. Especially because I want to be sure my mail is getting through to the other side of the planet.

As numerous others have commented, as long as the ability to use or respond to Read Receipts is OPTIONAL why would this present a problem?

Yes, for some privacy is a concern, but certainly not for all users in all instance. Certainly that is not the case if the users have agreed to use Read Receipts, as many do.

The scenario mentioned in the Apr 30, 2015 post by "ADMIN The Team!" seems to present it more as an etiquette issue than a true privacy issue.

And, of course, for those who consider it to be a privacy issue they can choose to simply not use the Read Receipt feature or not respond to Read Receipt requests, etc.

Additional requests for this featured have continued to be posted right up through this very time. But the last comment from "ADMIN The Team!" is way back in Apr 30, 2015.

Another thing to consider is that since that time you have added business features. And, of course, it is VERY common practice to sometimes use Read Receipts for business related email.

If possible, could you please post an update as to whether or not this feature is being considered/re-considered?

Thank you!

Add a 'Read Receipt' which the person receiving the email can choose to send or not.
A question could be displayed when the email is opened which says:

The sender of this email has requested a 'Read Receipt' do you wish to send one? Click Yes or No.

Then if they don't want to send a 'Read Receipt' just click 'No'.

leave it to the user to activate or deactivate in settingds

I would like to be able to use the SMTP features, Delivery Status Notification (if the remote server has implemented it, I would receive a message indicating that the message was accepted for delivery), and Message Disposition Notification (e.g., "Request Reading Receipt", usually the receiver gets a prompt from the email client and can decide whether or not to send the receipt), and also message Priority and Importance headers. For reading receipts the receiver should decide whether or not to send the receipt, but they know that you, the sender, would like a response. Also, I would like to be able to choose to send a read receipt if it is requested and I am the recipient.

I was wondering about this, because the settings for this app are overly simplistic.

Does this mean that the protonmail app does not respond to read receipt requests?

I agree, this is a privacy issue — this is not a feature I want in an email client.

There are times when its absolutely imperative to have a read or delivery receipt. It's a standard option on many email services. Please consider adding.

yesss, please.

I agree the user should decide

I agree that I want the option to not have a read receipt or delivery receipt sent when the send requests one. Adding the ability to request a read receipt would also be good to have.

A read receipt on self destructing email would be a useful feature and in no way is a privacy issue.

and me too

can you provide a feature to have a return notification of delivery of email?
this is important for my industry
thanks
