sendgrid-php VS fernet

$customers = array() foreach ($emails as $i => $email) { $customers[] = array( 'email' => $email, 'name' - $names[$i], 'accountId' => $accountIds[$i], ); } foreach ($customers as $customer) { // https://github.com/sendgrid/sendgrid-php/blob/main/USE_CASES.md#send-an-email-to-a-single-recipient }

To use the API instead of SMTP, you can use the SDK. https://github.com/sendgrid/sendgrid-php

SendGrid has a pretty good PHP library which should help you getting started sending bulk emails. They also have support for templating which is very helpful when wanting non-techy types to edit emails.

(in case you want to see the framework is in https://github.com/pragmore/fernet, I still need to work with the docs and stuff)
