20265 releases

  1. Bit SMTP 2.0.1Latest

    • Fix: Accented and non-Latin text (for example Bengali, Arabic, Chinese, emoji) no longer arrives garbled; emails use the site’s character set again, as WordPress does.
    • Fix: HTML emails from plugins such as Bit Form and WooCommerce arrive as HTML instead of raw code.
    • Fix: Multipart and calendar emails keep their format over SMTP, PHP mail, Gmail, Microsoft 365, and Amazon SES; other API providers receive the HTML or text part.
    • Fix: One invalid address no longer stops the whole email; it is skipped and everyone else still gets the message. If no recipient is valid, the email fails with a clear reason in the logs, and the test email form rejects such addresses.
    • Fix: Resending from the logs keeps plain-text and multipart emails as they were.
    • Fix: OAuth sign-in problems with Gmail and Microsoft 365 are reported as needing reconnection instead of being retried.
    • Fix: The logs table fits your screen, with a wider layout on large screens; the routing source picker shows long plugin names and stays on screen on phones.
    • Fix: Other installed copies of Bit SMTP no longer appear in the source list.

  2. Bit SMTP 2.0.0

    • Feat: Dedicated API integrations for SendGrid, Amazon SES, Mailgun, Postmark, Brevo, Resend, Mailjet, Zoho CPaaS (ZeptoMail), SparkPost, and Cloudflare Email Sending (Beta), plus Gmail and Microsoft 365 via OAuth, any SMTP server, and PHP mail().
    • Feat: Multiple connections with a priority order and automatic fallback; enable, disable, and disconnect connections without deleting them.
    • Feat: Retry queue with backoff for temporary failures, failure classification, and connection health checks.
    • Feat: Smart routing by recipient, from address, subject, or source plugin; the source picker lists every installed plugin.
    • Feat: Real delivery tracking through provider webhooks, registered automatically when you save a supported connection; Amazon SES events via signed SNS notifications.
    • Feat: Failure and health alerts by email, webhook, Slack, Discord, and Telegram, sent once per incident with recovery notices.
    • Feat: Analytics dashboard, optional open and click tracking, and read-only Email Analytics abilities on WordPress 6.9+.
    • Feat: Richer logs — Cc/Bcc, message IDs, filters, resend history, and CSV export — with scheduled retention clean-up.
    • Feat: Settings page with export/import and a configurable send timeout; import connections from WP Mail SMTP and Easy WP SMTP with WP-CLI.
    • Feat: WP-CLI commands and wp-config.php credential constants.
    • Feat: Multisite support, guided setup with help on every field, a refreshed accessible theme, and dark mode.
    • Security: Credentials encrypted at rest with AES-256-GCM; hardened webhook and outbound API paths; usage data is shared only after a one-time opt-in.
    • Privacy: The admin font is now bundled with the plugin instead of loaded from Google Fonts; all external services are documented in this readme.
    • Requires PHP 8.1 or newer and WordPress 5.9 or newer. Installs on older PHP show an admin notice and stay inactive.
