Guides & TipsSPF fails with PermError when evaluating your record takes more than 10 DNS lookups, nested includes included. Count them with dig, remove dead includes, use ip4/ip6 for your own servers and move bulk senders to subdomains.
Platform UpdatesNetSendo v2.11.4 fixes a Docker healthcheck that marked the webserver container "unhealthy" on every installation, even though the site worked fine. The fix lives in docker-compose.yml, so pulling the new image is not enough. Here is how to apply it.
Guides & TipsApple Mail Privacy Protection prefetches images in the background, so Apple Mail opens no longer mean reads. Here is what opens still tell you and what to measure instead.
Platform UpdatesNetSendo v2.11.3 fixes birthday, subscription-anniversary and "date reached" automations, which never ran, and stops CRM follow-up sequences of deleted contacts from failing every five minutes.
Platform UpdatesNetSendo v2.11.2 makes webinar room chat work, including auto-webinar chat scripts and moderation. It also fixes timezone bugs in webinar scheduling, corrects watch-time tracking and fixes date math that broke after the move to Carbon 3.
Platform UpdatesNetSendo v2.11.1 fixes 502 Bad Gateway errors that could appear after an update. The webserver now restarts automatically whenever Docker Compose recreates the app container.
NetSendo v2.11.0 includes the NetSendo MTA in every installation, adds a "Can this server send mail" check for port 25, PTR and SPF, and fixes the SPF guidance for self-hosted sending.
Guides & TipsMost cloud providers block outbound port 25 on new servers. Test it with nc, then send through an authenticated relay on 587, 465 or 2525, or request an unblock if you run your own MTA.
Platform UpdatesNetSendo v2.10.0 adds a built-in AI connector. Paste your installation's /mcp address into Claude, ChatGPT, Cursor or Hermes, sign in, choose permissions, and you're done. No API keys and no Node.js on your computer. The first page load is also about a quarter of its old size.
NetSendo v2.9.0 turns the built-in MTA into a working mailbox provider with per-domain DKIM and dedicated IPs from Vultr and Linode. It also adds one-click unsubscribe links, a rebuilt dashboard and important security fixes.
NetSendo v2.8.7 fixes a compose file bug that stopped Podman installations from updating since 2.8.0, which left them without the security fixes from 2.8.5 and 2.8.6. Here is what changed and what you need to check.
Guides & TipsOne SMS holds 160 GSM-7 characters, but a single character outside that alphabet (ł, á, an emoji, a curly quote) switches it to UCS-2 with 70 characters per segment, and every segment is billed.
Platform UpdatesNetSendo v2.8.6 is a security release. The Telegram webhook now checks a secret token, approval buttons only act on plans from their own account, and no single account can redirect the shared bot. Here is what changed and how to upgrade.
Platform UpdatesNetSendo v2.8.5 fixes an API security issue. The Brain API now has its own brain:read and brain:write permissions, saved secrets no longer leave the server, and the queued CSV list export requires subscribers:read.
NetSendo v2.8.4 replaces Brain's daily token cap with a configurable per-task budget. One heavy task no longer stops your AI work for the rest of the day.
Guides & TipsGmail rejects mail with 550-5.7.26 when neither SPF nor DKIM passes and aligns with your From domain. Read Authentication-Results, sign DKIM with your own domain, align the Return-Path and publish DMARC.
Platform UpdatesNetSendo v2.8.3 makes Brain AI safer and more predictable. Sends now use only the message their own plan created, dry runs change nothing, failed steps are recorded as failures, and chat goals move on without help. You can also approve plans directly in the chat.
Platform UpdatesNetSendo v2.8.2 makes the global Brain mode apply to every agent, sends every Brain service to the AI model you chose, restores chat command understanding and fixes GPT-5, o-series and Gemini 2.5 support.
NetSendo v2.8.1 fixes a bug where the AI Brain kept saying "Daily AI token limit reached" every day after you hit the limit once. The counter now resets every day, so the web and Telegram chats start answering again the next day.
NetSendo v2.8.0 introduces a contributor programme that earns free GOLD licences. It also adds DKIM selectors for Amazon SES, safer SPF and DMARC generators, one timezone rule for all messages, and translations for about 140 panel messages.
NetSendo v2.7.2 fixes SMS campaigns that were never sent from the panel. It also repairs the test SMS button, the send_sms MCP tool and WordPress plugin signups, and keeps each account's mailboxes, SMS providers, tags and contacts separate from other users on the same instance.
NetSendo v2.7.1 fixes a Docker bug that made the Live Visitors page connect every browser to ws://localhost:8085. It also makes MCP_API_KEY readable again and adds a test that keeps the problem from coming back.
Guides & TipsBack up first, then change the image to mysql:8.4 and replace the removed --default-authentication-plugin flag in the same edit. The server upgrades the data directory on its first start, and there is no in-place way back.
Platform UpdatesNetSendo v2.7.0 adds semantic search to the Brain knowledge base, so the AI gets the knowledge that matches each task. The release also adds a rich-text editor for template text blocks and makes Docker updates safer by letting only one container migrate the database.
Platform UpdatesNetSendo v2.6.0 adds an anonymous daily usage report that stays off until an administrator turns it on. You can see exactly what would be sent before you agree, switch it off at any time and have past reports deleted. This article explains how it works.
NetSendo v2.5.2 serves the panel's logos, favicon and fonts from your own server and drops the Tailwind Play CDN from public webinar pages. Your subscribers' browsers stop sending requests to third-party hosts, and the pages look exactly the same.
NetSendo v2.5.1 removes the Google Analytics script that every installation loaded in the panel, sign-in page and partner portal. Your panel now loads no third-party tracking. Here is what changed, why it matters and how to update.
NetSendo v2.4.0 enforces the GOLD plan in the application itself. A/B tests, auto and hybrid webinars, and OpenRouter/Ollama now require an active GOLD licence. Here's what changes, what keeps working after a licence ends, and how to prepare your installation and API clients.
NetSendo v2.3.2 sends new Cloud administrators a welcome email in their own language instead of a password reset. Password emails now link to your own installation, and the sign-up link disappears once an administrator exists.
NetSendo v2.3.1 changes how new versions reach NetSendo Cloud. Once a release image is published, the hosting catalog gets a signed notice right away, so hosted instances no longer wait for a nightly registry check. Security fixes are installed at once. Self-hosted installs don't change.
Guides & TipsVerify your domain with Easy DKIM, leave the sandbox, create Region-specific SMTP credentials and send through email-smtp.<region>.amazonaws.com on port 587, with bounces and complaints handled.
Platform UpdatesNetSendo v2.2.1 fixes the 502 Bad Gateway error that appeared when you opened the email editor directly from a link, a bookmark or a page refresh. Here is what caused it, what changed, and how to update.
Platform UpdatesNetSendo v2.2.0 adds RFC 8058 one-click unsubscribe, text/plain parts in every email, reply detection, 140 MCP tools for AI agents, and funnels that actually branch. It also moves to MySQL 8.4, Laravel 13 and Inertia 3, and fixes a long list of bugs.
