MXToolbox has a free tier for basic lookups with daily limits. Continuous monitoring and email alerts require a paid plan starting around $129 per month. The free tier is good for occasional checks but not for ongoing DMARC or SPF monitoring.

What is a good MXToolbox alternative for small business?

InboxGreen is designed specifically for small businesses. It offers a free SPF/DKIM/DMARC check with no signup required, a $29 one-time FixKit that generates copy-paste DNS records for Cloudflare, Namecheap, Google Workspace, and more, and DMARC monitoring from $19 per month. It focuses on email authentication fixes rather than network diagnostics.

Can InboxGreen replace MXToolbox?

InboxGreen replaces MXToolbox for email authentication use cases (SPF, DKIM, DMARC, blacklist checks). It does not replace MXToolbox for network diagnostics like SMTP testing, traceroute, BGP routing, or ping. Choose based on your actual need.

Which is cheaper for DMARC monitoring, InboxGreen or MXToolbox?

InboxGreen is significantly cheaper. DMARC monitoring starts at $19 per month for up to 5 domains with daily checks and email alerts. MXToolbox monitoring starts around $129 per month for one domain. For small businesses monitoring a few domains, InboxGreen offers much better value.

Pricing comparison

MXToolbox's free tier is useful for occasional lookups, but monitoring and alerting require a paid plan starting at around $129/month for the Standard plan. That covers one monitored domain with email alerts.

InboxGreen is significantly cheaper for the same core use case:

Free: Full SPF/DKIM/DMARC check, blacklist check, 8 free tools - no account needed.
FixKit ($29 one-time): Copy-paste DNS records formatted for your registrar + PDF guide. No subscription.
Monitoring ($19/month): Daily checks, email alerts when records change or fail, up to 5 domains.

Frequently asked questions

Is MXToolbox free?

MXToolbox has a free tier that covers basic lookups (blacklist check, MX lookup, SPF check) with daily limits. Features like continuous monitoring, email alerts, and uptime tracking require a paid subscription starting around $129/month.

Can MXToolbox fix my emails going to spam?

MXToolbox can diagnose whether your SPF, DKIM, and DMARC records are present and valid, but it does not generate ready-to-use fix records or explain what to do next in plain language. You'll still need to figure out the correct DNS records yourself. InboxGreen's FixKit generates the exact records you need, formatted for your specific DNS provider.

Does InboxGreen replace MXToolbox?

Not for network diagnostics. If you need to test SMTP servers, run traceroutes, or diagnose IP routing, MXToolbox has tools InboxGreen does not. For the core job of checking and fixing email authentication (SPF, DKIM, DMARC), InboxGreen is more focused and more affordable.

What is the cheapest way to monitor DMARC?

InboxGreen's Monitoring plan at $19/month covers daily DMARC, SPF, and DKIM checks with email alerts for up to 5 domains - making it one of the most affordable options compared to MXToolbox (~$129/mo) or EasyDMARC (~$18-45/mo).
