It is also a question of costs. With around 40 different forums, the solution of DragonByte mail is a costly element for me.
With that level of volume I'd be happy to work with you to ensure you wouldn't need to renew 40 licenses every year
If I go that route longterm, it has to create additional value vs. this free addon.
Mail is the next addon on my list to review all existing feature requests, and I know
@Alpha1 has logged a fair number of them that interface with AWS - I'm hoping they are possible without having to setup complicated developer credentials on Amazon's end
Since several years I asked for throtteling as a new feature for DB Mail. Many people asked for it at Xenforo. But no progress in this direction. THAT would be an important feature for my use cases.
Throttling is a feature just now, but it's on my list to improve (the suggestion @ my site will be flagged as Approved as soon as I start going through all the old suggestions) and will be updated in the next version
I can not see what kind of important features have been added over the last 3 years which would save me money, time or make daily task easier for me to keep my old users in the forum. If you pay almost 40 USD each year for this addon, I would expect more innovation and more open mind for user's suggestions.
What's an important feature varies from person to person of course, but I hear you. I am committed to eventually reviewing
all suggestions made for
all my XenForo addons, it will just take some time. DB Mail is, as mentioned previously, next now that Donate has been updated.
History has shown that DB Mail is what it is and you can not expect that within the next 3 years important features for my use cases will be added. So why should I spend my money there?
You could say that for any other addon to be fair, and I think history will also show that I have kept the addon up-to-date with both bug fixes and updates for new XenForo versions.
Then this was a misunderstanding. I verified my old email addresses already years ago, when I started with Amazon SES.
Since then I have no problems with Amazon SES. Everything works fine including soft and hard bounces within XF, thanks to this SES addon. I do not see an added value of DB Mail regarding this point for me.
Amazon recommend you re-verify emails every 6 months. DB Mail will keep track of the last time an email account is verified since install. Recently I've added support for multiple 3rd party verification tools (since the old, free, "SMTP connection on port 25" trick is blocked now) and also made it so whenever the forum sends an email to a user, their last validation date is also updated such that your validation costs are kept low.
If you never send out mass emails to your entire user base (minus banned accounts etc) then this might not have much value to you, but it can be quite important should your server ever suffer a security breach and you need to email people a new password (or at least a notice to change it). Ask me how I know (it was CyberPanel).
If this addon works with XF 2.3 longterm, I do not see what DB Mail offers me on top, which would be worth 40 US per year per forum.
I know this is semantics but renewals are not subject to the full cost. For DB Mail specifically, the renewal cost is fixed at €27.45 at the time of writing
I still have to send out over Amazon SES with DB Mail. So what is the advantage?
I would say if you have no need for sending limitations (e.g. X mails per hour - a feature that will be improved in the next version to allow for more fine grained control) and you have no need for newsletters that users specifically subscribe to or digests that are automatically generated based on your forum's popular content, then the main benefit would be the ability to re-validate your existing user base.
While re-validation can get costly, especially with the number of forums you own, it can potentially be worth it to avoid a situation where you have to explain to Amazon why you sent 20k emails and 4000 of them bounced. From personal experience their support staff have been helpful and understanding, and I've actually been given three or four chances - I don't know if I would risk it a fifth time

I have also read anecdotes @ this site of users who have been hit once and never got their account unblocked.
Amazon support staff very explicitly said that SES is not a mailing list validation service and without any kind of tracking for when the last time you emailed a given user, you really have no way of knowing whether that email address is still "good".
