For more information, please see: https://github.com/PHPMailer/PHPMailer/releases/tag/v5.2.18 ; https://github.com/advisories/GHSA-5f37-gxvh-23v6 ; https://nvd.nist.gov/vuln/detail/CVE-2016-10033

If you don’t have Composer, you can download PHPMailer manually from GitHub and include it in your project.

Step 1: Download and Install PHPMailer Download the PHPMailer library from here and extract it to your project directory.

Then make a form and use PHPMailer.

PHPMailer, as the name suggests, is an email-sending tool for PHP. It offers a straightforward and reliable approach to sending email messages from PHP applications. Security remains a top priority for the PHPMailer creators. It is equipped with built-in support for SSL/TLS encryption, ensuring the protection of email messages against interception and tampering. Moreover, it implements safeguards against common email injection attacks, effectively countering header injection and body injection vulnerabilities.

Have you tried using PHPMailer? mail() really isn't great and ends up being a lot more difficult to use. Phpmailer uses (or can use) SMTP (like Outlook or whichever email app) and is better at HTML and attachments and all that.

I found I have good experiences with a real email address provided by my domain/web host, and then I use the PHPMailer Class to send the message with the appropriate headers and what not.

The easiest way to send e-mails (from a beginner POV) is PHPMailer connected to an existing and configured SMTP server. Does your school has one? If yes, you're all set.

$customers = array() foreach ($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.
