Track Email Client Types


Mailchimp has a feature that gives you stats of the top email clients your contacts are reading your emails in. This is very helpful for formatting and prioritizing optimization for different email clients; for example, Outlook is a nightmare for CSS spacing and if I knew that a large majority of our contacts were using it (which I suspect), I would focus more energy on that design process, whereas if a negligable amount of contacts were using Outlook, I would make it less of a priority. Thanks!

We should be able to export this data as well.


Definitely and almost absolutely necessary feature. My company is continually designing based on the wrong platform even though I know their lists do not use the email client they want to design for. Hard to refute their requests without being able to show proof.


This feature would be very helpful, sad to realize this is not available and creates extra work to do this analysis, vote for getting this into development 


Considering the Apple iOS 15 privacy changes approaching in the fall of 2021, which will have an impact on all email marketing, it seems as though having visibility into our entire database in terms of % of email clients in which marketing emails were opened would be hugely important data to have easy access to. We will want to know how big of an impact this will have on our specific database. While viewing this data on an individual email basis is useful, it doesn't provide visibility as a whole across the database.

Could really use this! Client is looking at alternative email clients... HubSpot tech support said 50% of the emails will end up in the promotions folder for Gmail client users. Not a good selling feature. Especially since I can't find out what email clients thier contacts are using. 


Gmail has 18% of the email client market share in May 2021. That’s not that high of a percentage. Not sure what percentage is personal vs business.


Please add this capability. 


Increasingly important to know what email client you db records are using given Apple's recent move:


Bump for visibility.


Please create this feature considering the recent Apple iOS 15 MPP change.


Marketers always need to prove our legitimacy, and we look bad not being able to advise executives on what kind of impact this change will have on our databases and email reporting, other than "open rates will be inflated" and "Litmus estimates 49% of the market uses Apple Mail" which we know doesn't translate to many industries or those with ABM TALs.


We really need this feature. It's very frusterating trying to get a picture of how you are engaging with your contacts through individual email reports. I'm shocked there is no support for this and that it is not currently planned. It seems like such a simple implementation.


Bumping. Others already raised the issue concerning Apple's announcement in June about MPP.  With iOS15 rolling out soon—even though people have to opt-in to MPP—being able to filter contacts by which email client they use is going to be critical for (email) marketers.


Any updates regarding when this feature will be available?


YES please – this would be amazingly helpful and save us so much time in reporting.

This feature is critical as Apple is rolling out Mail Privacy Protection.


This needs to happen!


I second @sjunnila@EKirkland, and @MoreLeadsPlz. It's vital that we stay ahead of this update.

As a support specialist, I would love to see this capability, as I see customers asking about it while chatting with us. 🙂


You KNOW when an employee of the company making the features, wants a feature, it's probably something that everyone else wants and has been waiting for.




Since the last news update in early 2020.

Hi All,


Thanks for your comments on the idea. This isn't planned for development in the next quarter. For transparency and clarity, I'm updating this issue to 'Not currently planned' for the time being. We will re-evaluate in the future and we will update this idea if anything changes. Please feel free to upvote and continue to leave feedback on this thread.

It would be cool to get quarterly updates on feature requests and where they're at in the dev. que, or if they're even in the que at all. I know that new features also make for excellent marketing tools! So if it's a matter of having to wait till a new campaign is launched, something like, "might be coming out later this year," would be just generic enough for a yes but not a when. Just a thought 😆


No pressure 🤣


@amacdonald any update on this getting pushed to the forefront of the roadmap for HS developers? this is imperative to have with apple ios update and I'm shocked there hasn't been more HubSpot communication around this. Can we get an update or please let us know if there's another idea that is similar and the developers are reviewing. 




This would be so helpful for me too!


Definitely need this feature! Especially due to the new IOS 15 privacy updates, would be extremely helpful if we could segment apple vs non-apple users.


Spoke too soon... forgot that's just page traffic 😓

That's how badly I want this feature 🤣🤣🤣
