The PHP client documents PHP 7.4 or later, Guzzle 7, API credentials and MailSend requests with recipients and attachments. Minimum compatibility is separate from runtime security.

Scope: These sources establish a customer-side PHP integration. Provider infrastructure impact or remediation for PHP2Shell (CVE-2026-109618 / CVE-2026-109619) remains unverified. SDK availability or minimum PHP requirements are not proof of remediation.

What users should do

Check verified senders and API credentials and test delivery, failures and attachments with test recipients; check patched PHP runtime status separately.
