Hi,

I am trying to develop an application system for educational facilities to manage waiting lists, etc. In one part of my app I use an email button to allow the administrator to send an email to a long list of emails. I am testing with over 100 email address in the bcc. The idea is that the admin user clicks an email button and a prepopulated email popup with all the email address of applicants filled in the bcc. I have tested it on mobile and it works fine and opens up in the mobile phones gmail client.

However, I am testing this on a desktop but nothing happens when I click the email button. I know that the issues is not a desktop email client set up issue as it works when I remove the long list of bcc email addresses and my outlook client opens up fine.

So does anyone know if there is a limit to the number of email addresses that can be specified in an email button?

And secondly if there is a limit can anyone suggest an alternative for sending an email to a large amount of recipients. I know I could use the Mail.App in a google app script but I understand there is a daily quota based on the number of emails you are trying to send to.

Thanks in advance,  
IB

Probably you can try SendGrid, I’m not sure of their quota, but have seen them mentioned on here.
