I'm sure I read recently that it was possible to change the maximum number of emails that can be sent using the transactional mail in CiviCRM. Did I imagine this or can the hard coded limit of 50 be set to another value?

I am not sure where you can change the limit of sending 50 transactional emails in one go....but I would like to warn you that if you change that limit the chances of getting blacklisted will increase!– ErikH - CiviCooPOct 28, 2017 at 10:53

It's recommended to use CiviMail for larger mailouts. It's worth understanding the potential consequences of using "simple CiviCRM mail" to do mails in bulk; eg:
- Harming your own site's spam reputation by sending many emails without spam compliant unsubscribe links.
- Harming CiviCRM platform email reputation by using CiviCRM without respect to spam compliance.
- Timeouts and performance issues when trying to deliver large numbers of emails in a single request.
- ... ?
So, this has long been hard-coded in an attempt to avoid people changing it. The limit is no longer hard-coded; it's become a hidden setting: simple_mail_limit. You should be able to change this setting from the default either by using the CLI tool cv:
cv api setting.create simple_mail_limit=99
Or by adding a setting override in civicrm.settings.php:
global $civicrm_setting;
$civicrm_setting['other']['simple_mail_limit'] = 99;
See configuring hidden settings in CiviCRM for more info, and do take note of advice here to reflect on why you think you need to change this value!

2I highly recommend understanding why this isn't a setting exposed for easy configuration; good starting points may be CRM-20905: Simple mail : Make max emails a hidden config instead of hardcoded value set to 50, PR discussion #10693 (Not sure if the extension mentioned here to expose the setting as UI exists?) and PR discussion #10705 Oct 28, 2017 at 20:16

Many thanks for your response(s). I fully understand the rationale and consequences. However I have one user who needs to send to a small group of a little over 50 contacts and I need to humour him! Now that we are using Mosaico there is no real difference to send using the bulk or transactional email. Given your response I am now able to make up my own mind about the way that we approach this.

2Great! And yeah, I agree this may fit your situation well - this is a community resource and I'm also writing with future readers in mind who might not recognise the difference between using CiviCRM's direct and bulk mail systems if the warnings aren't clear :D If this response was helpful, please remember to mark the answer accepted - this will help future people in your situation to resolve the same!
