<p dir="auto">Having an AWS account and exploring it fully, I can tell you that group email to <50 there is a HARD LIMIT with the SES Mail Service.</p>

<p dir="auto">I never doubted that you were experiencing such limits. My points is that these limits are imposed by the service provider. Just to illustrate my point, if you were to run your own SMTP server on your own machine (real or virtual or cloud), you could choose from many SMTP servers, none of which have any built-in limitations on addresses per mail.</p>

<p dir="auto">Also, the lack of any tech support at AWS is another problem. Had to get this answered by the Sales & Marketing groups. Tech Support was clueless!</p>

<p dir="auto">That's terrible to hear, but unfortunately not surprising.</p>

<p dir="auto">I found free versions of SMTP service providers to investigate - those with $0 cost options. <a href="https://www.emailtooltester.com/en/blog/free-smtp-servers/#gmail" style="color: #777777;">Here</a> you will find some analysis of SMTP sender servers and their limitations.<br>
Notably as well is the limitation of Google Services’ Gmail servers. Many people have Google but fewer are aware of the services and/or limitations of same.</p>

<p dir="auto">Personally, I'd stay away from Google and Microsoft, as neither are too concerned with complying with standards.</p>

<p dir="auto">My SMTP Server use case, in real terms is for 50-100 emails pieces/mo from my domain address (this one) that comes with 100 BCC senders group (irregardless of To or BCC) in any single email. The limits of the domain servers have been shrinking and limitations due to BW and spam rules have been on the rise, in case you don’t know. FWIW, my server has been vetted for DKIM, etc. … Good luck.</p>

<p dir="auto">You might have better luck if you use a mailing list server so that each recipient gets their own individually-addressed email, with proper "List-" header fields and so forth. That might help lower the likelihood of your messages being categorized as spam.</p>
