The new Email Campaigns Tool in WHMCS 8.0 is pleasing, especially the Schedule Campaign option.
However, the Email Campaign functionality currently has a hardcoded limit of 25 emails per run and can run every 5 minutes by default. This 5 minute is based on our cron setup. It can be every minute or every hour.
There isn't currently a way to override this limit.
If my cron is configured to run every 5 minutes, then every 5 minutes, I can only send 25 emails. If I have 10k customers, my mail campaign will take more than a day to complete.
For a time-critical mail like a maintenance notification would be very difficult with this setup.
I request to provide a feature where we can overwrite this setting based on our requirements.
