Quick answer
Mailinator - Mailinator wins for most builders because its free tier is broader and more realistic for testing workflows, while Pingram’s free plan is mainly a small outbound messaging allowance.
How the free tiers compare
These products solve different problems even though both touch email and SMS. Mailinator is a testing and QA tool, so the free tier is built around disposable inboxes, temporary storage, API access, webhooks, routing rules, SMS testing, and load-testing features. That makes it useful for validating sign-ups, OTPs, and password resets without much setup. Pingram is a send-oriented messaging API, so its free tier is narrower and more operationally capped: 3,000 emails per month, 100 SMS per month, unlimited domains, and 30 days of logs. If you need to test message flows, Mailinator is the better free starting point. If you need to actually send a modest amount of email or SMS from an app, Pingram is the more relevant free tier. The paid paths also diverge: Mailinator scales into higher test-volume and team features, while Pingram’s pricing is a simple jump to a $20 Pro plan and then a much larger enterprise add-on.

After you outgrow the free tier
Mailinator’s paid ladder is flat-priced at $79/month for Business, $159/month for Business Plus, and custom Enterprise pricing from $699 and up, with costs driven by inbox and team-scale limits such as domains, seats, storage, and email throughput. Pingram is simpler: the first paid tier is Pro at $20/month, then an Enterprise Addon at +$800/month for larger org features. For small-team usage, Pingram is cheaper in absolute dollars, but Mailinator’s free tier covers a much broader testing surface before you have to pay.

Bottom line
For the most common builder use case, Mailinator is the better free tier because it is designed for testing whole email and SMS workflows, not just sending a small amount of messages. Pingram is the better fit if your immediate need is a modest outbound messaging API with real sending quotas and logs. Once you outgrow free, Pingram starts cheaper, but Mailinator gives more practical value before you pay.
