Just wanted to offer some feedback as a long time user of AMS on the current support/licensing model. Not necessary to suggest any changes, but food for thought, perhaps?
I know you have switched a couple of times between perpetual updates/support and fixed period (e.g. 1 year) over the years.
Certainly in recent time, the update cadence has left me reluctant to 'renew' my access to updates/support to potentially only get one or more updates in a year (if that), particularly as compared to some of the historic release cycles.
I understand from your perspective that it's probably a catch-22 in that you need to see some return on investment in your time developing the software, but equally as a user I want to see some benefit from my investment in a 'renewal'.
With that in mind, if update cadence is likely to remain as-is, is there potential for a lower priced option (rather than effectively purchasing from scratch again) to renew access to future updates? I've no idea (and wouldn't necessarily expect you to share) what the figures look like in terms of number of purchases/active users, but I doubt that I would be alone in being willing to contribute a lower amount on an ongoing basis for access to future releases, on the basis that they are likely to continue for the foreseeable?
As it stands, I'm waiting for the implementation of DKIM before I consider renewing - having put AMS behind a load balancer primary to offload the encryption whilst we awaited the update to OpenSSL 3, that's largely mitigated some of the issues with the aged OpenSSL version my current version is running - so no real incentive for me to upgrade at present in the absence of DKIM and/or other additional/improved features.
