Hey @n1fdadmin,
Thanks for reaching out! Gmail is a great solution for most/casual users, but there are definitely scenarios where is isn’t a good fit.
Sending to emails to more than a dozen people or sending more than a few emails at once are the two scenarios users will most often encounter that won’t work with Google.
Google has a limit on how many emails you can send per day, per hour, and per second. Generally, the first two limits are high enough that its pretty hard to ever pass that. However, when it comes to emails per second, the limit is around 3 (don’t recall the exact number off the top of my head, but something like that).
So given this limit, even if you took the email with 250 people and were able to split it up into 10 emails to 25 users, you would still encounter an issue as you would be well above the rate limit Google allows to send per second. We don’t have any way to “delay” emails or similar to get around this.
For your use case, I would recommend looking into Mailgun as they would be a much better solution. They are specially geared for situations like this where you have to send more high volume (both recipients and bulk send) – they don’t have the restrictions that Google has. It’s a bit tedious to setup, but they offer free accounts which provide 10,000 free emails/mo. We have a guide on setting up Mailgun if you decide to give that a try.
Hope that helps! Happy holidays ??
