I have this small setup where I have a Google Sheet, Google Appscript and Google form.
The user needs to input data in a Google Form - and once the sheet (linked with Form response) receives the updated row - a script is triggered which takes the data from the row and feeds it into the sheet and sends mail to the selected set of users.
Now the problem I am facing is that I need to send this mail to approx 100-150 people, however Googel appscript does not allow me to send mail to more than 30 participants at a time.
I understand that I need an Email service for this, however, I am unable to find any good solution wherein I can store my templates and the user just fills up data fields and shoots the mail.
Maybe because I am very new to this tech field so thats why.
Can anyone please guide me as to what is the setup I need to use for my purpose?
Thanks!

The first thing you need to do is to keep the BCC list as an array until it's necessary. This will allow us to make chunks out of it. This means removing the .toString() at the end of assigning bccmail.
Then, we need a custom function to send the email in batches of emails. I'm calling that function sendMassEmail.
function sendMassEmail(bccList, subject, plainBody, htmlBody, attachments) {
for (let bcc of chunks(bccList, 30)) {
GmailApp.sendEmail(
'',
subject,
plainBody,
{
htmlBody,
bcc: bcc.join(','),
attachments,
},
)
}
}
Chunks is a function that does exactly that, gets the elements of an array in chunks. My favorite implementation for this case is by using a generator.
I've kept the plain text body as it's important to generate it if you are sending it, as it is shown in most clients on the Inbox. Also, some of them can only read this ones (think smart watch).
The last argument (attachments) is optional.
Here is an example on how you would use it:
sendMassEmail(
bccmail,
sub.toString(),
'', // Should probably change it
htmlforemail,
file1,
)
Note that it's better to use toString() than concatenating into an empty string.
