Testimonials
“Remove email from spam folder”
Unspam provides actionable insights for improvement, allowing me to make changes to my emails with confidence. This helps me ensure that our emails reach the inbox.
“Improve email deliverability, best tool!”
The heatmap is particularly useful because it shows you precisely which parts of your email pique interest and how to enhance them to increase CTR.
“Fixed spam issues with email checker”
Just a couple of emails and I've already fixed several deliverability issues. Wow, this is awesome.

Everything teams ask before choosing a plan: billing, limits, agencies, plan upgrades, and trials.
Is the free plan really free? +
Yes. The Free plan ships with a monthly allowance of spam tests, email previews, heatmaps, and inbox placements at zero cost, with the AI assistant included and no credit card required. Paid plans raise those monthly limits and unlock historical results.
What’s the difference between a spam test and an inbox placement test? +
A spam test scores a single message against deliverability signals (authentication, content, blacklists, HTML) before you send it. An inbox placement test sends your campaign to a seed list across Gmail, Outlook, Yahoo and other providers, then reports where each copy actually landed (Inbox, Promotions, Spam, or Missing). Most plans include both with separate monthly quotas.
Can I upgrade or downgrade later? +
Any time. Upgrades take effect immediately and Stripe pro-rates the charge against the unused portion of your current cycle. Downgrades take effect at the end of the current billing cycle so you keep the higher limits until then.
Do unused tests roll over to the next month? +
No, monthly quotas reset on your billing anniversary. If you regularly hit the ceiling, upgrading to the next tier is usually cheaper than buying overage.
What payment methods do you accept? +
All major credit and debit cards via Stripe. Agency and White Label plans can be invoiced annually, with a discount; get in touch via the support chat to set that up.
Do you offer a money-back guarantee? +
Yes, a 14-day no-questions-asked refund window on all paid plans. Reach out from the support chat and we’ll process it the same day.
Can I cancel any time? +
Yes, from the Subscription page inside your account, or by replying to any invoice email. No retention calls, no hoops.
How many sender accounts can I connect? +
Unlimited. Connect as many sending accounts as you send from on any plan, and we never charge per inbox or per seat. Your monthly quota is metered by tests, not by senders.
