Sending HTML Emails in Laravel: SMTP & API Tutorial

A Laravel 9+ tutorial explains how to send customized HTML emails through either SMTP or the Mailtrap API using Laravel’s mail configuration and Mailable classes. It covers generating mailables, defining envelopes, content, sender details, recipients, attachments, headers, and Blade-based HTML templates that can include dynamic data safely through escaped variables. The SMTP workflow uses Mailtrap domain verification and environment credentials, while the API workflow requires installing the Mailtrap PHP client, configuring a Mailtrap transport, supplying an API key, and sending mail through an Artisan command or specified mailer. Additional examples demonstrate inline image embedding, file attachments, multiple recipients, CC and BCC fields, direct use of the Mail facade as an alternative to mailables, and email styling guidance that favors embedded or inline CSS over external resources for better client compatibility and deliverability.
