SpeedyMessaging

This is the official WordPress client for SpeedyMessaging , a paid transactional email service. It is not a general SMTP configuration plugin: it does not connect to arbitrary mail hosts, and it has no server/port/encryption fields. It speaks one service’s API, and it exists to make sending from that account correct rather than merely possible.

Routes wp_mail() through the SpeedyMessaging API so every email your site sends — WooCommerce receipts, Contact Form 7 submissions, password resets — goes out through your own mailbox, without changing any of those plugins.

What this does that a mail-configuration plugin does not

Sending here costs money per message, and the account can run out. That makes the hard problems different from “which host do I point at”, and it is where this plugin does its work:

• You are never charged twice. Every paid call carries an Idempotency-Key , so a plugin that fires wp_mail() twice, or two overlapping cron runs, produce one delivery and one charge — not two. Retrying a paid send is normally the thing you cannot safely do; here it is safe by construction.
• Attachments arrive openable, or not at all. Every file is uploaded first and sent by reference. Testing against the live API showed that passing a file inline is accepted and then never stored — the recipient gets a message claiming an attachment nobody can open. This plugin never sends that way, and if a file cannot be uploaded it hands the message to your normal mail rather than delivering it gutted.
• Running out of credit holds mail, it does not lose it. Queued messages wait, an admin notice appears, and they send once the account is topped up. Nothing is discarded.
• Consent is tracked and enforced. A do-not-contact list is checked on every send, with signed one-click unsubscribe links that cannot be edited to suppress somebody else. Privacy exporters and erasers are registered, so a GDPR request covers what the plugin stores.
• It stays out of your way. The plugin’s screen lives under Settings. The only notices raised elsewhere mean mail is not being delivered right now — they are dismissible, and they never appear while you are writing a post.

Nothing is ever silently lost. Email tries each configured transport in turn and falls back to this site’s normal mail if none of them work, so a mistyped credential degrades delivery rather than stopping it:
