Check your sender reputation before Gmail does.
Gmail, Outlook and Yahoo judge every message on the same public signals: SPF, DKIM, DMARC, blocklists and DNS. We check your domain layer by layer, grade it A to F, and hand you the fixes in the order that matters.

Read rankingHow a ranking is made
Most "best email marketing" lists give you an opinion. These give you the inputs, so you can disagree with a number instead of a vibe.
Start from what buyers ask
Ten phrasings of the buyer's question, each run five times through AI search, pooled and filtered. The platforms that recur are the ones compared.
Score on a published rubric
Eight weighted dimensions that sum to 100. Prices come from official pricing pages read on a stated date, and we look up each vendor's own SPF, DMARC and BIMI.
Date it, sign it, keep it open
Every page carries its checked date and a named author, Yevhen Kralych. Vendors and readers can challenge a fact, and fixes land on the page.

ReadFrequently asked questions
How are the email marketing rankings scored?
Scored rankings use eight weighted dimensions that add up to 100, printed on the page with the weight rationale and score bands. Every price comes from the vendor's official pricing page read on a stated date, and we look up each vendor's own SPF, DMARC and BIMI records as one dimension of the score. The methodology section explains each step and how to challenge a result.
Can a vendor pay for a position in a ranking?
No. Positions, badges and reviews are not for sale. Vendors can dispute a fact or a dimension score with evidence from an official page, and the decision is recorded in the page's update log.
What is a sender reputation score?
It is a single estimate of how trustworthy your domain looks to mailbox providers. Gmail, Outlook and Yahoo each keep their own private score. Ours grades the public signals they rely on (authentication, blocklists, DNS and infrastructure) from A to F so you can fix what is visible before it costs you the inbox.
Is SenderDirect free?
Yes, every ranking and every tool is free with no signup. Checks run in your browser against public DNS, so there is nothing to store and nothing to sell.
Why do my emails go to spam even with SPF, DKIM and DMARC?
Authentication proves who you are; it does not prove anyone wants your mail. Complaints, bounces, low engagement and sudden volume spikes still send mail to spam. Our spam-folder diagnosis walks through each cause.
Pick the right platform, then check your domain.
Start with the ranking for your situation, then run the full deliverability check on the domain you will send from: SPF, DKIM, DMARC, 15+ blocklists, MX and reverse DNS, graded A to F.
