MxToolbox
Email deliverability problems cost revenue and reputation. Your AI agent runs MxToolbox DNS lookups, blacklist checks, SPF/DKIM/DMARC validations, and SMTP tests on demand during conversations. Your team gets diagnostic answers instantly instead of switching to a browser tool.
Your AI agent runs MxToolbox lookups for DNS, email authentication, blacklists, and connectivity tests, delivering diagnostic results directly within your team's conversations.

See how IT teams and marketers use MxToolbox diagnostics through AI conversations to troubleshoot deliverability, verify DNS, and maintain email infrastructure.
Your marketing team reports that campaign open rates dropped sharply. Your AI Agent runs a blacklist check, SPF validation, and DKIM lookup for your sending domain through MxToolbox, all in one conversation. It identifies that your IP was listed on two blacklists and your SPF record has a syntax error. The team has actionable root causes in minutes instead of spending hours manually checking each diagnostic tool.
Your team is setting up email for a new product domain. Your AI Agent runs MxToolbox checks for MX records, SPF, DKIM, and DMARC on the new domain, confirming each record is properly configured. It catches that the DMARC policy is still set to 'none' and recommends moving to 'quarantine' before launch. Complete email authentication verified through a single chat thread.
A client asks your digital agency, 'Why are my emails going to spam?' Your AI Agent runs a comprehensive MxToolbox diagnostic suite on their domain: blacklist check, DNS lookup, SPF, DKIM, DMARC, and SMTP test. The agent compiles findings into a clear summary, identifying two missing DKIM selectors and an overly permissive SPF record. Your agency delivers a professional audit through conversation.

FAQs
The agent uses MxToolbox's Blacklist Lookup API, passing a domain name or IP address. MxToolbox checks the target against over 100 DNS-based email blacklists and returns the status for each. The agent presents which lists have flagged the domain and which are clear, all in a conversational response.
Yes. The agent can run all three lookups sequentially for any domain. SPF retrieval uses the SPF lookup endpoint, DKIM uses the DKIM endpoint with domain and selector, and DMARC uses the DMARC endpoint. Results from all three can be compiled into a single email authentication summary.
Tars requires your MxToolbox API key, which you obtain from your MxToolbox account under API Settings. The key authenticates all lookup requests and usage counts against your plan's monthly quota. Free accounts get a limited number of lookups, while paid plans offer higher limits.
No. The agent runs MxToolbox lookups in real time during each conversation. DNS records, blacklist results, and email authentication data are fetched live and used only for the active interaction. We do not cache or store diagnostic results separately.
Yes. The Monitor Status endpoint retrieves health details for all monitors configured in your MxToolbox account. The agent presents the current status of each monitored domain, including any alerts or degraded conditions, giving your team a quick infrastructure overview.
The MxToolbox website requires you to visit the page, enter a domain, and read the results manually for each check. Tars lets your team run multiple diagnostics through conversation, compile results, and get actionable summaries without leaving their chat tool. It also works across WhatsApp, Slack, and your website.
Yes. MxToolbox provides HTTP connectivity tests and Ping diagnostics through the API. The agent can check HTTP response status for a domain and run ping tests to measure network latency, giving your team a broader infrastructure view beyond just email.
The agent can check your remaining API quota using MxToolbox's Usage Check endpoint before running lookups. This returns your plan type, remaining lookups, and quota reset timing. If you are approaching your limit, the agent can prioritize the most critical checks.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
