How to A/B Test Effectively In Shipping Time Optimization

In general, we don’t recommend A/B testing as a primary metric for evaluating delivery time optimization performance. Because sending time optimization generally increases the overall health of the email, the benefits of using this approach compound over time. Split testing doesn’t take into account any of the long-term benefits of using send time optimization. At best, a split test will only tell you how much boost STO gave a specific email. That said, many users will still choose, or be asked to “A/B” test the shipping time optimization. This guide will help you avoid some of the most common mistakes and get the most accurate results possible.

Let the system have time to learn before evaluating Seventh Sense uses machine learning to build profiles on the engagement of its subscribers. To give the system a head start, the system creates initial profiles based on your historical engagement data from HubSpot or Marketo. These initial profiles are biased towards times when you have Cook Islands B2B List sent your emails and you will not see a full degree of optimization until the system has had more time to learn. For example, if you previously sent all your emails at 9 a.m. M. Thursdays, at 9 a.m. M. And the hours after Thursday will seem to be better times than they really can be. Fortunately, Seventh Sense is designed in such a way that this bias is resolved relatively quickly.

But It May Take A Few

Months of consistent mailing with STO before the system is fully optimized. For this reason, we generally recommend that you wait at least 90 days before taking the Seventh Sense split test. Note that split testing may reduce the benefits of throttling Hardware spam filters, such as Barracuda, often impose a rate limit. This means that when a certain number of messages arrive at the server at the same time, the spam filter can be activated. By using STO, your messages are less likely to trigger these filters because they are not sent all at once. If during an A/B test, the blast cohort is sent first and the rate is limited, it is likely that STO messages sent later will also be blocked.

Cook Islands B2B List

For this reason, we recommend that when split-testing STOs, you always send the burst last . Note that the explosion cohort can negatively affect STO performance When you split a list in two and send half the mail with STO and half as a blast, email service providers (ESPs) don’t see it as two separate messages. They see it as a message that is sent over time. This can introduce a number of biases into the test that almost universally benefit the blast cohort and reduce the performance of the STO cohort. Why would the explosion benefit and the STO cohort suffer? Think of it this way: remember when you worked on group projects in school?

Was There Always A Kid

Who didn’t do any work, but managed to pass because of the hard work of the other kids? That is the wonder. Email service providers view email messages holistically. Instead of evaluating the STO cohort and the explosion separately, at the ESP, they are working on a group project. This means that any increase in engagement generated by STO will increase the chances of the blast cohort reaching the inbox. What happens if I put the explosion first? Will that fix the problem? Not really. As we discussed earlier, putting the burst first will remove the choke buff from STO. Also, in the same way that STO will increase open rates in the blast cohort. The blast cohort can reduce the performance of the STO cohort.
