What Warmy Free Deliverability Test is

The Warmy Free Deliverability Test is a no-cost check that sends a message to a Warmy seed address and reports inbox versus spam placement, SPF, DKIM and DMARC status, blocklist presence and content issues that commonly trigger filtering.

It is designed as a first diagnostic: run it before a launch, after a DNS change, or when open rates drop, and you get a concrete list of what to fix rather than a general score.

It sits in the inbox placement & seed testing part of an email stack - see where mail actually lands across providers. In practice it is the right pick when your priority is: a quick health check before committing to a bigger audit.

What it does well

The capabilities teams rely on most are no account required, auth and blocklist checks included, shareable result link. Taken together these cover the day-to-day work in this category, and they are the features worth testing during a trial rather than reading about.

It combines placement, authentication and blocklist checks in one free run and links each finding to the fix, instead of returning an isolated score.

In real use the strongest points people report are completely free; fast, readable report.

Pricing tiers

Warmy Free Deliverability Test is a free product. Free, no account required for a basic run.

Pricing pages move often, so confirm the current figures with the vendor before you budget. The number worth modelling is not the licence fee on its own but the cost per delivered email once bounces, suppressed contacts and spam-foldered sends are taken out.

Ideal customer profile

• Best fit: A quick health check before committing to a bigger audit.
• Where it sits in the stack: Inbox placement & seed testing - see where mail actually lands across providers.
• Budget profile: Free - suited to teams comfortable with this commercial model.
• Probably not for you if: single-send snapshot rather than continuous monitoring would block your team.

What it connects to

Warmy Free Deliverability Test is commonly wired into Any SMTP sender, Google Workspace, Microsoft 365, Amazon SES and SendGrid. Check that the specific objects and events you rely on are covered, not just that a logo appears on the integrations page - shallow connectors are a frequent source of rework.

Where it falls short

No tool in this space is complete on its own. With Warmy Free Deliverability Test the trade-offs to plan around are single-send snapshot rather than continuous monitoring. None of these are reasons to avoid it - they are the gaps another layer of your stack needs to fill.

A single test is a snapshot of one message from one mailbox. Ongoing placement needs repeated testing across providers, which is what the full seed-list product does.

A useful test before committing: send a real campaign through your intended setup, then check where it actually lands across Gmail, Outlook, Yahoo and your customers' corporate filters. Tooling that looks identical on a feature list often behaves very differently once reputation and authentication are involved.

How it fits a deliverability stack

Deliverability is decided by four things: the reputation of the sending domain and mailbox, the quality of the list, correct SPF, DKIM and DMARC authentication, and proof of where mail actually lands. Warmy Free Deliverability Test covers part of that picture. The mistake most teams make is buying four separate products for those four jobs and still having no single place that tells them whether the last campaign reached the inbox.

As a Warmy product, Warmy Free Deliverability Test shares the same reputation data, seed network and reporting as warm-up, inbox placement testing, email verification and DMARC monitoring - so the four jobs above stay in one view.

Use it to find the problem; use warm-up, verification and DMARC monitoring to remove it.
