i am building an app in which users can sign up for a mail notification system that sends emails based on specific events linked to each user's account and i was testing using zoho's mail along with nodejs (nodemailer) for the automation, i noticed when specific events fired close to each other and there were alot of emails sent at once zoho blocked my email, which is understandable, my question is if there is an option or workaround with zoho for this because i can't estimate how many and when the emails are sent, and the emails are time-sensitive so i cant implement a query to slow down the process, if not then what would you guys suggest ?
