Enable A/B testing in workflow/automated emails


I was disappointed to see that I can't do an A/B test in an automated email:



Marketo (a HubSpot competitor) allows this functionality.

Can you add this to the product sometime?

It's particularly helpful with a Welcome email sequence which is key to on-boarding new customers.

Hey folks!


The ability to A/B test to automated emails is now in public beta. This enables you to try new tactics and optimize your email sending. To A/B test an email, open the email editor and click "run a test" in the top left.

Hi all,


Quick update here. Again thank you for your patience and feedback here. We are currently moving to testing this feature. It will take a bit of time as it is a big change on the email infastructure. I will update here as soon as it is in Beta. I wont give an exact timing as it depends on what we find in testing. Anyone who has signed up will be in the first release group, if you have not asked support for this please reach out and they can add you to the beta list.


Thank you, it is very close now.

Hi Everyone,


Thank you so much for all your interest and comments in this forum. I am the Product Manager on Marketing Email and I wanted to jump in here as I have been closest to this project for past few months. We are so close, we had hit a couple of small bumps that set us back with the complexity of this build. We are in the final stretch and we are talking about delivering this in September. We have had 2 teams involved in building this and we are so excited to release the Beta as soon as we can. I will update this post as soon as it is ready for beta.

Thank you for your patience and continued interest in this project.

Hi all! Two quick updates for you on this:


Number 1: Progress is going well, we have our new A/B framework in good shape and at the moment we're focusing on the new in-app features needed to begin/end and analyse this new type of A/B test for workflow emails. This is a big update on what is currently available for batch emails, and will give you the ability to end an A/B test and start a new one on the same email without needing to rebuild the email over and over again. Getting very close now! 


Number 2: Moving forward this feature, the updates on it's release and all feedback will be handled by my colleague @jaleonard19. Jake is also a PM here working on our marketing email tools and has actually been the one spearheadding this feature for some time now so you'll be in great hands. 


Jake is currently working on our release plans and will be sharing a public beta signup form with you all as soon as it's ready. Thank you all again for your feedback and suggestions. Looking forward to seeing the impact this will have for you all.

Will do @petersherlock93

Dec 11, 2019

Will do @EJVFernyhough ! We'll be sharing a beta sign up form with everyone on this post when it's available so everyone will have the opportunity to sign up once it's open.

@AJernigan can do Smiley Happy

Hi @ridingforlife I can definitely share more. At the moment we're making good progress but factoring in the upcoming US and EU holiday season it's unlikely that we'll be hitting beta-ready in Q4 but safe to say that we'll have a beta in Q1 2020. As soon as we have an open beta we'll offer it up to everyone in this thread to give it a try.

Hi all, just to keep everyone updated on our progress here, we've been making decent headway with the infrastructure planning and development roadmap for this feature and are making meaningful progress towards a beta.


There's still a lot of moving pieces here so we don't have a concrete date on when we'll be opening up a beta but I wanted to keep you all in the loop and confirm that we're definitely focused on this and are actively working on it.

Aug 14, 2019

Thanks @petersherlock93! Just a case of good ol' miscommunication 🙂  The "on pause" here just means that we were still deep into the infrastructure and reliability work needed for this (and other) functionality. It was by no means deprioritised or taken off the roadmap, just needed to get the ordering right on the priorities to make sure we didn't put the cart in front of the horse, so to speak.

Aug 13, 2019

Hi @petersherlock93  (and all following along). I can confirm that this isn't the case, A/B testing of automated emails is still very much a priority for us.


For the past few months we have been focused primarily on work on the underlying infrastructure of email, to ensure speed, stability and reliability of the overall platform and user experience. We're nearing the end of this work right now which enables us to continue to build on top of the email tool and makes it possible for us to build more net-new functionality in a stable and scalable way, A/B testing of automated emails being a great example of that. 


While there hasn't been much news on this specific feature lately, it's something that is very high on our roadmap and now that we're seeing results from our infrastructure and performance work we're able to refocus our efforts on bringing these new features to the product. Rest assured that it's still something we're focused on. 


While we aren't yet at the stage of a beta for this feature, I'd recommend checking out these resources (one and two) from the HubSpot blog that provide interim solutions and as soon as we have a beta that's available for everyone I'll share a signup form for everyone here to try out. Thanks again for your feedback and for keeping the momentum going here.

Hi all, I wanted to share a quick status update with you on this. We've spent some time researching options for this feature and are making good progress. We'll soon be heading into a dedicated research phase and as we get close to a beta of this we'll open it up to everyone on this post to get early access. Please do keep your feedbac/upvotes coming, we really appreciate it.

Nov 16, 2018

Thank you all for sharing your feedback and use cases on this. The product team is currently thinking about how to solve this, and will post updates here.

A/B testing an entire workflow to see what places could be improved to improve conversion rates.

Great idea though for now! I might try that and see how it goes. 


Can't wait to test out the feature when the beta opens



Hubspot representatives, please advise on when A/B testing in automation will be implemented. This is a must-have feature for creating working email automations. 


Mad that this is not possible? 


Not just the testing of one email vs another, but what about a completely different workflow entirely? Loads of competitors have this and it is a real hindrance to businesses that want to continue to test and learn. 


I also cannot believe Hubspot do not support this functionality for automated emails or transactional emails. Really need to prioritise this!


Need this one!


This is so important. Still can't believe HubSpot do not support this functionality. 


It looks like this has been in the 'planning' stage for a couple of months now... Any update or ETA for us?


If smart content analytics worked, (which they don't) that would help


A must have. We need it.



As others have said, absolutely critical to be able to test in workflows. It's so limiting to not be able to do this.


As this is in planning, it would be great to get a timescale on it!


I could be late with this but I think this works:




I was able to create an A/B test with 2 different templates and copy. I am yet to test it but so far it looks good.


UPDATE: This doesn't solve it, unfortunately 😞



This is really surprising to me. It's really a basic and crucial feature in an automated workflow, I would have expected it to be a part of HubSpot, with the price tag that it comes with.


Are there any plans on implementing this?


Yes, it's quite shocking considering we just invested in Hubspot Marketing and I used to use Outreach for Outbound emails.


I thought I posted was the solution but it turns out I was wrong as this can only be used with an email list and there is still no way to A/B test in the automated workflow.


I will need to figure out how to use Zapier and make a workaround. Insane! 



+1 here. Other tools have this feature so it makes no sense to not have it on HubSpot. It should be a native function not a zapier/workaround function.




They made me some videos on how the workaround works and it involves using two separate workflows rather than just two emails equally tested in one workflow - quite shocking.


No timeline was given either for when the feature will be available...


its absolutely ridiculous. this has been an issue for over 2 years and the amount of energy that has to be put in to create the a/b test is assinine. our workflows have as many as 5 emails in them... that would require like 40 if/then/rotators.

+1, agreed with everyone else on this.

+1, this functionality is so important for testing the performance of workflows.
