I've been using Encharge since 2022 (bought the 2021 LTD) and I can't imagine using any other email software.

Let's just look at one tiny aspect of their Flow system for automations - the Wait step. In this one step, you have two options - wait for a specific period, and then wait for a specific time. These can be used alone or in unison. For the specific period, you can use minutes, hours, or days (and if you want to wait a day and a half, just put 36 hours). Then for specific time, you can choose which days of the week you'd like it to be delivered (say M-F) or a specific date in the future. And then you can choose a specific time on that day or a time range. And you can choose to have the time be calculated based on the subscriber's time zone, if available. All this detail in just one of the steps!

You can also drill into so much detail when choosing parameters for segments. I can make a segment of everyone who has clicked a particular link in my emails for the past 30 days, 60 days, etc. Then I can use all the other filters to make it even more refined - have they been on my list for a year? Do they already own the product (via product tag)? Did they ever click the link to stop getting a similar promo? Do they own a similar product?

It's just amazing the level of detail you get with this! It's like owning a Lego set that you can build into whatever configuration you need for a specific task.

I hope I can keep using it for decades to come.
