PHP email SDKs

PHP support is dominated by Laravel-friendly SDKs. Symfony Mailer transports are the second pattern.

PHP teams increasingly run on Laravel or Symfony. The right question is which provider has a first-class transport, not just a raw HTTP SDK.

reading this as developers picking email infrastructure

The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.

Applied to PHP SDKs, that means weighing developer experience, SDK breadth, idempotency keys, and operating track record ahead of the rest, against password resets, receipts, and magic links shipped from application code.
