This page is designed to help you find out whether SpamRate.is is good and if it is the right choice for you.
I was the backend developer on a project where the marketing team ran our email campaigns. They were using five or six separate services for it, because, in their words, none of them gave the full set of tools they needed.
I spent a weekend putting together something that ran all of those checks in one pass, and connected it to real mailboxes. It was meant to stay an internal tool. A few months of testing later it turned into this.
SpamRate sends your campaign to real mailboxes at Gmail, Outlook, Yahoo and Zoho, then reports:
• where each copy landed, including which tab, since Promotions and Updates are different problems • SPF, DKIM, DMARC, blacklists, headers and content from the same send • monitors that repeat the test and email you when placement drops
You get one test without an account, and three a day with a free one. Pro and Max add higher limits and the automated monitors. There is also a lifetime plan running until the end of summer, if paying once suits you better than a subscription: https://spamrate.is/lifetime
Worth saying plainly: seed mailboxes have no history with your domain, so this measures the filterable part rather than engagement. That's still the part you can fix before sending.
I'd like to know how you check this today, and whether anyone has found a way to notice a slide into Promotions before reply rates quietly drop.
P.S. I recently added a WordPress plugin that tests the standard WordPress emails and the WooCommerce customer emails in one click. It's been submitted to the WordPress plugin directory and is waiting on review, which takes a while. Until then it's available as a zip on the site if you want to try it.

Narrow, clear focus
Based on the name, the site appears to be a spam-rating or spam-checking tool. A single-purpose tool like this is usually simple to understand and quick to use. I can't browse the site, so please verify what it actually does.
Possible quick, low-friction checks
Tools of this type often let you check an email, domain, or message without a complex setup. Confirm on the site whether it requires no signup or offers a free tier.
Potential help with deliverability
If it scores content or sender reputation, it could help you spot spam-trigger issues before sending campaigns. How useful it is depends on how transparent and accurate its scoring is, which I can't confirm.
Small and midsize senders: SaaS and product teams, newsletter publishers and email marketers, developers responsible for transactional mail, WordPress and WooCommerce owners, and agencies handling deliverability for several clients.
The marketing team on a project I worked on used five or six services to track deliverability, because none of them covered everything. I built an alpha over a weekend and hooked up real mailboxes. A few months of testing later it stopped being an internal tool.
Real mailboxes at Gmail, Outlook, Yahoo and Zoho, not a predicted score. It tells you which tab the message landed in, not just inbox or spam, because Promotions and spam need different fixes. Authentication, blacklists, headers and content come out of the same test.
Most tools answer one piece: your DNS is fine, or your content score is fine. Neither says where the message landed. SpamRate does placement, authentication, blacklists and content in one test, keeps the history so you can see when things changed, and reruns on a schedule with alerts. The first test needs no account.
Python, FastAPI, PostgreSQL, Redis and Celery, plus a long-running asyncio service that holds IMAP connections to the test mailboxes. Jinja templates with Tailwind on the front, Docker everywhere. The plugin is PHP.
