Send Images to RSS vs SendForce Mail SMTP Relay – SMTP and

Send Images to RSS bridges the gap between large websites and small emails, by replacing images in your feed with smaller, email friendly images, and attempting to add markup which email clients can handle. Between larger monitors, retina screens, and better image optimization, the images we serve up on our websites are larger than they’ve ever been. RSS to email services such as MailChimp, however, are constrained to what email clients can display, which is small, small, small. And although it’s possible to try to style images with a max-width in your emails, not all clients will honor it (I’m looking at you, Outlook). Send Images to RSS makes it easy to create beautiful, email friendly RSS campaigns, with minimal setup required, regardless of your feed setup. Full Text RSS Feeds If your site’s RSS feed is set to Full Text, this plugin makes sure your emails look more like your website: Replace overly large images with email friendly size images. Convert galleries from thumbnails to full width images. Add email friendly styling/alignment to your images. Summary Text Feeds If you’ve used Summaries as your RSS feed settings, this plugin has not been for you. Until now. As of 3.0.0, Send Images to RSS brings the awesome to you, too. Here’s the magic for your Summary feed: Add the post’s featured image to your excerpt. Choose the size and alignment. If no featured image is set, the plugin will use the first image uploaded to the post. Set a custom length for your RSS summary/excerpt. Pick the number of words you want your summary to have, and the plugin will aim for that, but with the added bonus of making sure the final sentence is complete. If you add a manual excerpt to your post, because you like to have full control, the plugin will properly use that instead. Automatically add a custom “read more” link to the end of every post summary, to keep your feed pointed back to your site. Known (non)Issues This plugin should work with any theme. Some themes and plugins do modify the feed for their own purposes. Where possible, I’ve tried to account for them: For summary feeds, the Yoast SEO RSS link is removed (the full text feed and front end output are not changed). For summary feeds, the excerpt filter added by the Woo Canvas theme is removed (the full text feed and front end output are not changed). For summary feeds, this plugin will replace the image settings for Display Featured Image for Genesis for versions 2.3.0 and later (because this plugin is smarter). If you’re using Display Featured Image for Genesis 2.2.2 or lower, this plugin will concede graciously. But you should update, please. For full text feeds, this plugin will not duplicate featured images if they are being added by Display Featured Image for Genesis–you will want to disable that feature in Display Featured Image for Genesis. NOTE: it is up to you to check that your feed output is still working, especially in your email system of choice, once it’s installed. I’ve attempted to set it up to handle XHTML or HTML5, and function even if your feed is wonky, but please double check, and let me know if you have issues, and if so, what specifically they are. Props Special thanks to Gretchen Louise for her summary feed contributions. Spanish translation offered by Web Hosting Hub

SendForce Mail Relay is a free, open-source WordPress SMTP and email-API plugin that fixes the “WordPress emails not being delivered” problem. Send WooCommerce order emails, Contact Form 7 / WPForms / Gravity Forms submissions, password resets, registration confirmations, and any other wp_mail() traffic through Amazon SES, SendGrid, Mailgun, Brevo (Sendinblue), Postmark, Zoho ZeptoMail, Gmail API, Microsoft 365, or any standard SMTP server — with full email logging, queue, retry, and failure alerts. Why SendForce Mail Relay Free and open-source. Every feature is included — no premium tier, no email-volume cap, no provider paywall. 24+ providers, one plugin. Built-in presets and HTTP API integrations for major transactional email services — pick what fits your budget, deliverability needs, and region. Built-in debugging. Live SMTP debug log on test email, raw API request/response capture in the email log, “Copy Debug Info” button for support tickets, and WP-CLI commands. Designed for developers and agencies who need to diagnose email problems fast. Multiple connections with automatic fallback. Configure a primary connection (e.g. Amazon SES) plus a fallback (e.g. Mailgun). If the primary returns an error, the fallback takes over — no email lost. Supported email providers HTTP API sending (recommended — faster and more reliable than SMTP): Amazon SES (AWS Simple Email Service) SendGrid (by Twilio) Mailgun (by Sinch) Brevo (formerly Sendinblue) SparkPost Postmark Zoho ZeptoMail Microsoft 365 / Outlook (Microsoft Graph API) Gmail / Google Workspace (Gmail API) SMTP2GO SMTP.com Elastic Email SocketLabs Moosend SendLayer Mailjet MailerSend Mandrill (by Mailchimp) Resend Netcore Email API (formerly Pepipost) SMTP sending (works with any provider, including custom servers): Gmail / Google Workspace SMTP (smtp.gmail.com) Microsoft 365 / Outlook SMTP (smtp.office365.com) Yahoo Mail SMTP Zoho Mail SMTP Turbo SMTP Any other SMTP server (host, port, username, password) Features Multiple connections with automatic fallback — configure a primary connection (e.g. Amazon SES) plus a fallback (e.g. Mailgun, SMTP, or PHP mail). If the primary returns an error, the fallback is attempted automatically. Both attempts are logged so you have a full audit trail; recovered emails carry a “Recovered via fallback” badge in the log detail view. Smart Routing Rules — send different emails through different connections based on rules you define. Match by recipient domain, recipient pattern (glob), sender email or domain, source plugin (auto-detected for WooCommerce, Contact Form 7, WPForms, Gravity Forms, Ninja Forms, Fluent Forms, Forminator, Easy Digital Downloads, MemberPress, LearnDash, MailPoet, BuddyPress, bbPress and more), subject contains, time of day, or weekday. Rules are evaluated top-down (first match wins) and can target a single connection, a round-robin pool, or WordPress phpmail(). Includes inline rule editor, master enable/disable toggle, “Test Routing” tool, and a “via rule:” badge on the Email Log so you can see exactly which rule fired for any send. One-click provider presets — pre-filled host, port, encryption, and API endpoint for every supported provider. Just paste your API key or password. Email Log — every outgoing email logged with status, recipient, subject, headers, error message, and timestamp. Filter by status, search by keyword, filter by date range, export to CSV or JSON. Email Queue with retry — queue mode prevents rate-limit errors and timeouts on bulk sends. Failed emails auto-retry on exponential backoff (5 min → 15 min → 45 min). Email Test page — send a test email with live SMTP debug log output. Diagnose connection problems instantly. Failure alerts — push delivery failures to Telegram, Slack, Discord, Microsoft Teams, Google Chat, Pushover, or any custom webhook. Sender Identity override — force every email to use a custom From name and From address site-wide. Conflict detection — warns you if another SMTP plugin (WP Mail SMTP, FluentSMTP, Easy WP SMTP, Post SMTP, etc.) is active so you can deactivate it before things break. Encrypted credential storage — SMTP passwords and API keys are encrypted at rest using AES-256-CBC with a dedicated per-site key, so they survive security-key/salt regeneration. WP-CLI commands — wp sendforce test, wp sendforce queue process, wp sendforce log list, wp sendforce sysinfo. Developer hooks — sendforce_before_send, sendforce_after_send, sendforce_log_entry, sendforce_api_request, sendforce_api_response for extending the plugin without forking. WP_DEBUG_LOG integration — optional mirroring of SMTP and API debug output to debug.log. Automatic log cleanup — configurable retention period (default 30 days). Privacy-friendly — optional disable of email-body logging for GDPR / privacy compliance. Multisite compatible. Works with all major WordPress plugins SendForce Mail Relay hooks into WordPress’s core wp_mail() function, so it works with every plugin that sends email — including WooCommerce, Easy Digital Downloads, Contact Form 7, WPForms, Gravity Forms, Ninja Forms, Fluent Forms, Forminator, MemberPress, LearnDash, BuddyPress, bbPress, MailPoet (transactional), and any custom plugin or theme that uses wp_mail(). External Services SendForce Mail Relay is an email-delivery plugin. It does NOT connect to any external service automatically. A connection is made ONLY after you explicitly configure a provider and either (a) WordPress sends an outgoing email, or (b) you click “Send Test Email”, or (c) you enable a notification channel and an email-failure alert is dispatched. For each configured email provider, the data sent on every send is the same set of fields WordPress would otherwise hand to the local mail() function: the recipient address(es), CC, BCC, Reply-To, From name/address, subject, message body, headers, and attachments. No additional telemetry or analytics is transmitted by this plugin. For each configured notification channel (Telegram, Slack, Discord, Microsoft Teams, Google Chat, Pushover, custom Webhook), the data sent is a short status message you compose in the plugin (default: failed-delivery summary or daily summary).

Loaded entirely from your own server; no CDN call is made. Privacy Policy SendForce Mail Relay stores the following data in your WordPress database: Email logs (if logging is enabled): recipient email address, subject, headers, email body (optional), sent status, error messages, and timestamps.

Email body logging can be disabled in Settings > Queue & Logging. Log entries are automatically deleted after the configured retention period (default: 30 days). All data is deleted when the plugin is uninstalled. We recommend adding a note to your site’s privacy policy if you log email content, informing users that outgoing email metadata may be stored.
