Feature Highlights: What Stands Out and What’s Missing
Here’s a look at what Mail-Tester actually delivers – and where it falls short.
- Blacklist Monitoring
- DKIM / SPF / DMARC Validation
- Deliverability Score
- Spam Testing
- Analytics & Reporting
- API Access
Let’s take a closer look at what Mail-Tester delivers with each of these features.
Blacklist Monitoring
Mail-tester checks the sending server’s IP against major blacklists as part of every standard test run. If a listing is found, the result flags it within the report – and the API response includes a dedicated blacklists sub-object that lists every service checked alongside the pass/fail result for that specific send.
DKIM / SPF / DMARC Validation
The SPF and DKIM check tool validates both records directly from the sending domain, and authentication results feed into every standard test report. The signature sub-object in the API response covers SPF, DKIM, and rDNS individually – each with its own score, diagnostic comment, and suggested fix where something fails.
Deliverability Score
Every tested email gets a score out of 10, built from SpamAssassin output, authentication checks, blacklist status, content analysis, and link validation combined. The goal is a clean 10/10 – and the main API response object returns both the final score and a short plain-language summary of what’s pulling it down.
Spam Testing
Spam scoring is the core function of mail-tester.com. Each submission runs through a default SpamAssassin installation, which flags content patterns, formatting issues, missing authentication signals, and HTML structure problems. The score is inverted from SpamAssassin’s native output so that positive numbers indicate a cleaner, safer message.
Analytics & Reporting
Paid manager accounts unlock daily, weekly, and monthly usage statistics alongside a 30-day searchable history of all tests run. The free tier keeps results accessible for 7 days with up to 3 runs per 24-hour window. White-label result pages with custom CSS are also available for teams embedding the tool into client-facing workflows.
API Access
After sending to a generated test address, a single GET call to the mail-tester endpoint with a parameter returns the full result as a structured JSON object. Six sub-objects cover the final score, message metadata, authentication results, body analysis, blacklist checks, and broken link detection – accessible to any paid account holder.

Infrastructure Checks
Mail-tester.com validates SPF and DKIM as part of every test run, but ongoing DNS monitoring and DMARC record inspection sit outside its scope. MXToolbox and Google Admin Toolbox cover that ground – useful companions for a complete authentication health check alongside mail-tester’s per-send diagnostics.
Mail-Tester Email Deliverability Software Pricing
| Pricing | Details |
|---|---|
| Minimum Price per Month | $50/month |
| Price per Verification / Credit | Pricing is per test run, not per address verified. The base pack works out to $0.10 per test at the 500-credit level, with the per-test cost dropping at higher volume tiers. Each credit covers one full spam and authentication diagnostic report for a single email submission. |
| Free Credits Available | Registering a paid account includes a small number of free tests to validate the setup before committing credits. The terms of service confirm this directly – new accounts automatically receive some free tests so users can evaluate the service before purchasing a credit pack. |
| Free Plan Available | es – the free tier allows up to 3 tests every 24 hours with no account or credit card required. Results are stored for 7 days. It covers the full spam score, authentication checks, blacklist lookup, and content analysis – the same report paid users receive, just rate-limited and with ads. |
| Free Trial Available | The free daily allowance effectively serves as a permanent trial. Up to 3 tests per 24-hour window are available without registration, giving teams enough access to evaluate the tool’s output and score quality before deciding whether a paid credit pack makes sense for their volume. |
Average Performer in the Email Deliverability space: While it provides basic email deliverability features, Mail-Tester lacks the innovation, scalability, and reliability to compete with top-rated businesses.

Feature Highlights: What Stands Out and What’s Missing
Here’s a look at what Mail-Tester actually delivers – and where it falls short.
- Spam Score Testing
- Link & Image Validation
- API Access
Let’s take a closer look at what Mail-Tester delivers with each of these features.
Spam Score Testing
mail-tester.com runs your outgoing message through a default SpamAssassin installation and flips the scoring so a positive result is a good sign. Send your newsletter once, get back a clean 10-point breakdown of what’s hurting – or helping – your deliverability before a single real subscriber sees it.
Link & Image Validation
Every URL inside your message gets checked for broken destinations, and image-heavy layouts are flagged when they skew the text-to-content ratio too far. It won’t rewrite your HTML, but it will tell you plainly which links are dead and whether your image balance is likely to raise a spam flag.
API Access
Paid accounts unlock both a JSON endpoint and an iframe embed, letting developers pipe mail-tester results directly into their own dashboards or client-facing tools. Credits don’t expire, and the integration setup is straightforward enough that a backend team can wire it up without dedicated deliverability expertise.
