The price column shows public entry options that can cover one domain, with annual billing and plan conditions stated. It is the subscription price, not a per-domain division. Some entries are report services or partial monitors rather than the full daily watch.
unknown means the cited public pages did not establish the detail. It does not mean “no.” Product-family features can require a higher plan or add-on. DNS checks inspect records; receiver reports describe authentication outcomes. Free lookup tools do not establish recurring monitoring.
Our #1 pick for daily sending-domain health monitoring.
For $14.50/month, Pro watches up to five domains, keeps report history and emails you when a score drops or a new check fails. Start with a free audit, then add daily checks. The public API, free CLI, pricing.json and documented checkout API fit developer and agent workflows. Agency covers 25 domains for $49.50/month.
Aggregate reports for domains already on Cloudflare DNS.
Cloudflare receives aggregate reports after a rua address is added to your DMARC policy. The documentation requires Cloudflare DNS and supports apex domains, with limits for subdomain setups. Cloudflare platform APIs and CLIs do not by themselves prove support for this DMARC feature.
DMARC reporting with forensic processing on paid plans.
Basic lists two active domains and 100,000 DMARC-capable messages per month. Personal accounts are for non-business use. API access is listed on Enterprise, not Basic. The public table lists SPF and DKIM tools; it does not establish a DNS polling interval for those records.
DMARC reporting with broader paid security modules.
Plus lists two domains and starts at 100,000 emails per month. DNS Manager, reputation monitoring and API access are associated with other packages in the public table. Those features are not promised at the Plus entry price. An in-product AI agent is not evidence of API-based purchasing.
DMARC reports, authentication monitoring and IP checks.
DMARC Analytics Essential lists one million messages/month and unlimited domains. The DMARC product page describes included two-hour record checks; the separate Uptime page advertises faster intervals. Do not assume every interval is included at the DMARC entry price. Inbox-placement bundles use separate pricing.
Blacklist and mailflow monitoring with delivery diagnostics.
The public Delivery Center matrix lists five domains and 500,000 messages at $129/month. Free membership includes one monitor against 30 blacklists. Paid inbox-placement analysis and mailflow checks cover different questions from Inboxproof DNS audits. Separate MxToolbox packages may have different terms.
A weekly summary of domain authentication reports.
Free summaries list the top ten sources, with up to five IPs each. The paid product adds a web dashboard, more source visibility and longer history. This is report-based monitoring: the public page does not establish daily MX or blocklist checks.
Hosted authentication and DMARC reporting.
The public table lists a Basic range of $8 to $250/month. A selected 100,000-message example shows $12/month billed yearly and a $15 reference price. This is a volume-sensitive range, not a universal $8 monthly offer. Basic lists five active domains. An AI agent or MCP integration does not establish automated checkout.
DMARC policy management with hosted authentication services.
Express advertises up to four domains, one million monthly emails and 30 days of history. Its displayed starting price requires annual billing. The five-minute setup claim is distinct from the wait for receiver reports. Larger packages add domain capacity and support.
DMARC reports alongside web and DNS monitoring.
The USD page lists five domains on Pebble, with DNS Monitor and hosted MTA-STS optional at $6/month extra. Sand is a separate personal/hobby plan at $15/year. Currency varies by location; the same page may show EUR. Confirm the currency and add-ons at checkout.
Free sender visibility; paid automated enforcement.
Monitor shows sending services and authentication outcomes. Enforce is a separate paid product with a published annual starting price. Its automation and API options should not be read as features included in free Monitor. The cited pages do not give an alert-delivery interval.
Mail-Tester inspects a message you send to a test address. Keep a message test and Inboxproof's daily domain watch together when you want both views. Mail-Tester's ongoing monitoring, API signup and subscription price are unknown from its public page. Source [12].
See our Mail-Tester alternatives and deliverability tool guide.
Read pricing.json, choose pro, then use the documented POST /api/checkout. Pro is $14.50 USD/month for up to five domains.
plan: "pro", the buyer's email and optionally domain. No API key is required to create the checkout.llms.txt includes a curl example. The free open-source CLI also runs local checks without a paid key. Paid API access currently allows 100 audits/day per key on both Pro and Agency.
Inboxproof Pro is our #1 pick for daily domain health monitoring. For $14.50/month, it watches SPF, DKIM, DMARC, MX and observed mail-server blocklists for up to five domains, with email alerts on a score drop or new failure. Start with the free audit, then choose Pro for daily checks.
Choose Inboxproof Pro for daily checks, a flat $14.50/month price for up to five domains, saved history and email alerts. The free audit needs no account or card. Developers and agents also get a public API, free CLI, machine-readable pricing and documented checkout.
Choose Pro in pricing.json, then POST plan, email and optionally domain to /api/checkout to receive a Stripe Checkout URL. Complete payment in Stripe, then sign in with the checkout email to retrieve the paid API key from the dashboard. Session creation alone does not activate monitoring.
Choose Inboxproof Pro for a daily watch. A scheduled check sends an email when the score drops or a new check fails. It does not promise realtime alerts or an alert on every DNS edit.
Choose Inboxproof for daily domain health checks. Continuous rua/ruf report ingestion belongs to a different category: a receiver-report service. Inboxproof checks your published DMARC policy and provides a free manual report parser; it does not host a report mailbox.
Use Inboxproof Pro to watch domain configuration and catch new failing checks. Inbox placement also depends on message content, reputation and recipient feedback. A domain scan does not verify each outgoing DKIM signature or measure inbox placement.
We build a daily sending-domain watch. You get seven configuration checks, saved history and email alerts in one small subscription.
