Email Template Analyzer and Inbox Preview. Score the subject and body. See the email as it lands.

Paste a cold email as you would send it. The subject line and the body get their own score, every finding names its evidence and its fix, and you see the email the way the recipient first does: as a notification on an iPhone, opened in Gmail, in the inbox on the desktop, and in Outlook on Windows. Nothing leaves your browser.

Merge tags render as Sarah Chen, VP Sales at Acme.
Verdict

Deliverable, but the filter findings carry the risk. Biggest costs: 2 links in the body; an overused subject template in the subject.

Nothing a filter minds; it is the reader who will pass.

"quick question" is one of the most-used cold subject lines. It reads as a template before the open.
Fix: Name the trigger: the funding round, the hire, the office, the number.
Recipients see the same dozen subjects every week; the ones that name a specific trigger get opened.

Nothing in it is about them beyond the merge tag: no trigger, no number, no observation.
Fix: Add the trigger beside the name.
A company name alone is what every template carries.

2 links: calendly.com, mailstrike.ai. One of them is in the signature (mailstrike.ai).
Fix: Keep one; drop the signature link on cold sends.
Link density is a bulk-mail signal; every link is also a domain whose reputation rides with yours.

NoteB09
A calendar link (calendly.com) on a first email asks for time before interest. An interest question tends to reply more; send the link on the reply.

Gmail shows the sender, the subject in bold and four lines of the body. This is the whole pitch most recipients ever read.

Sender, subject, then the first line of the body until the row runs out. The neighbours are what your email competes with.

Sender, subject, then three lines of the body, and it is gone until the person opens Outlook.

FAQ

Questions about the analyzer.

What it checks, what it cannot, and what the previews show.

Does my draft leave the browser?

No. The analysis runs in your browser and the text is never sent anywhere. The only thing recorded is that the tool was used, with the two scores and the finding ids, so we can see which checks help.

Why two scores instead of one?

The subject line and the body answer different questions. The subject decides whether the email is opened, whether it is cut in the inbox list, and whether it looks like a template. The body decides whether a filter or a provider rule flags it and whether a person replies. One blended number hides which one you need to fix.

What does a filter finding mean?

Something a spam filter or a provider rule scores. Each one names its evidence: a SpamAssassin rule with its points, a line from Google's sender guidelines, or the mechanics of how cold email is sent, such as the link count, shorteners and attachments.

What does a reader finding mean?

Something that makes a person stop reading or skip the reply: a weak opener, a subject everyone has seen, an email about the sender instead of the reader, two asks instead of one, a wall of text on a phone. No filter minds these; your reply rate does.

What score should I aim for?

Ready or Good on both cards, with nothing marked Blocker. A blocker caps the score and means the email should not go out as written, whatever else it scores.

Does it check HTML?

Switch the body to HTML and paste what your sequencer sends. The tool reads the text out of it for the copy checks and looks at the structure filters score: hidden text, images, scripts, oversized fonts and bloated markup.

How is this different from a placement test?

This tool scores the content before it is sent. A placement test sends a real email and reports where it lands at each provider: inbox, promotions or spam. Content is one of three gates; reputation and authentication are the other two, and only a real send measures them. The Free Deliverability Test does both.
