Ability to A/B test send time for emails

cmichellec

As a newer HubSpot user, it would be beneficial for A/B testing to allow testing the same email for different send times. We are trying to find the best time for regularly sending out emails and the size of our contact lists makes the manual workaround is very tedious. Has anyone found an easier way that cloning emails and splitting a contact list in half?

Thanks again for all the great feedback and comments on this idea. At INBOUND, we launched a Send Time Optimization feature which ensures you send emails at the best time for your audience (learn more here). I’ve heard from some of you that a native send time optimization feature may address the same need as A/B testing send times, and I’d love your feedback on that.

 

Does this new feature meet your needs, or do you still see unique value in A/B testing send times? Feel free to DM me your feedback or to let me know you'd like to set up a call. Thanks!

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 are investing in bolstering our email testing capabilities starting here. If you are willing to jump on a call to talk more about this functionality, and your specific use cases send me a direct message. I would love to chat more.

 

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.

A/B Testing is absolutely indispensable for an email marketing tool – not to have this functionality soon within the marketing professional would be a reason to change the tool. Send time optimization is so super relevant.

Still 100% behind this idea! We should be able to A/B test send times for emails.

Completely agree! A/B testing for times is crucial.

Would love to have this available, pretty basic feature for a tool like HubSpot.

@jaleonard19 Any new update on this? Been almost 2 years since the last update. This is a common feature in other ESPs/MAPs.

I am still hoping this ability becomes a reality! It would be super helpful to be able to pinpoint the best time(s) of day to send emails without having to clone and make numerous copies of the same email to figure this out. HubSpot, please add this functionality to the list!

A/B Test on send times

As we know, in Email Marketing there are different sending times that work better than others. It's a functionality that would help us a lot to take conclusions: being able to test if an email works better at 8 am vs 8 pm (for example).

This would be a great feature and extremely beneficial when it came to reporting on my campaigns!

Another common sense functionality that HubSpot lacks. With all of the comments and upvotes, I'm very surprised that this has not been put into planning yet. This would be wonderful to be able to do without manual intervention. After all, this is one of the best marketing AUTOMATION platforms out there and I'd be quite disappointed to learn that other platforms have this capability.

I agree 100% @millennnialmktr! For now, I just clone my email after I build it to conduct an A/B test for send time. It is more work because I have to split my send list as well, but by doing this, I have determined for a client that sending in the afternoon is better than sending emails in the morning. 

So hopefully soon, HubSpot will enable email send times as an A/B test.

@AVChrista how are you splitting your send list? I need to start testing send times and I'd like to save as much time as possible. 

AVChrista

@millennnialmktr I split my list evenly just based on contact count. I made one list AM and the other list PM. Then the following month I swapped them to have the former PM list get the AM email and vice versa. I did that to see if morning vs afternoon was a better send choice.

 

After two months of that, the data tells me that the afternoon (around lunchtime) send performs better than a first-thing-in-the-morning email.

Of course, we're always testing, but at least I can lean towards afternoon send times as having better open rates and engagement with the audience.

This idea would be SOOO incredibly helpful as we try to test out the optimal send time for our monthly email newsletter.

definitely need this! and for a/b testing based on local time send too pls

Wow, 59 (including mine) replies confirming this should be a basic feature available and still nothing? It's pretty humourous that not having the ability to send based on timezone because you are doing an A/B test completely negates the test. You need as much as uniform about the send as possible so you know what features are impacting the test. If you add the time variable in there, how can you accurately measure your test? This seems like a basic feature request that shouldn't be too resource heavy to accomplish. The work around is to not use your A/B test feature and send clones to measure the test results yourself. Why even have the A/B test feature if it's implemenation is flawed like this? Pretty please fix this! I beg you. 🙂
