I am using G Suite app "Form Confirmation Emails" to send a customized mail in response when a user fills the form and submits their details. Everything is going on well but after 100 emails the messages get bounced/blocked. Below is the exact message I get. Your message to email@example.com has been blocked. See technical details below for more information. The link they take me to is https://support.google.com/mail/answer/6596?visit_id=637316916397394156-1334392294&rd=1
I also understand that emails sent using Gmail API or via SMTP has the limit 100.
I am also using another ADD-ON autocrat for sending certificates for people who have filled the form automatically. Even this after 100 emails bounces/blocked because of the limit.
So my question is how can I increase this limit, is there any workaround.
