Free to use · A working work email is all it takes

Find what breaks in your email before the send button does.

Launchpad is the checklist our own delivery team works through before a Mandit Global campaign goes out, and you can run it too. Give it your sender details and your email body: it reads the authentication records, queries the blocklists, walks the links and inspects the HTML for the things that break in real inboxes. It then shows the message in Gmail, Outlook, Zoho and Apple Mail, and names the day and hour we would send it.

No subscription, and no card to enter. We verify your sending domain live the first time you open the tool, and from then on every check runs inside your own browser. Your email template is never uploaded to us.

The address you give us is the first thing the tool checks. We resolve its mail records live, so an address that could never receive mail does not get past this box, and once you are inside we send the checklist we work from ourselves before a launch. One message, and no drip sequence afterwards.

Nothing to install. No card. No countdown on a free trial.
The template stays in your browser; we never receive it or keep a copy.
Sign out whenever you like and the details we hold go with it.

1 Who is sending

Sender name

Sending address We read the sending domain for SPF, DKIM, DMARC and MX records, and check it against the blocklists.

2 What is being sent

Subject Aim for 30–60 characters.

Preview text (optional)

The email HTML

0 bytes

Where the email links to We also look for tracking parameters, shortened links and pages still served over plain http://.

3 Who receives it, and when

Where most recipients are

Second location (optional)

Your timezone Detected from your browser — change it to see the recommendations from your team's point of view.

Check the links live Each unique link is sent to a public CORS proxy to see whether it resolves. Switched off by default so your campaign URLs stay private, and the email HTML is never sent anywhere.

What the check covers

Authentication records
SPF mechanisms and how many lookups they use, DKIM selectors, DMARC policy and alignment, MX, MTA-STS, TLS-RPT and BIMI — all resolved live over DNS.
Blocklist standing
Your sending domain, its mail servers and every domain used in your links are queried against the main DNS blocklists, with the reason for any listing spelled out.
Links that need work
Relative URLs, pages still on http://, shortened links, redirect clutter, repeated destinations and a missing unsubscribe link.
HTML that holds up
Flex and grid layouts, web fonts, background images, oversized files, images with no alt text, and the balance between images and text.
Why a message reads as spam
The wording and the formatting that push a message towards the promotions tab or the junk folder.
When to send
A 14-day window scored in the recipient's own timezone, with weekends, holidays, lunch hours and off-hour sends taken out.

What happens to your data

We verify your email address against live MX records, which tells us the domain can genuinely send and receive mail. It is held on this device, so you sign in once. Everything after that runs in your browser: DNS-over-HTTPS lookups for the domains you enter, blocklist queries, and the live link check if you switch it on. Your template never leaves the page.

A DNS lookup from a browser is a solid first pass. It cannot prove where the message will land. If you want a genuine seed test across the main providers, ask us whether we can run one for you. The score and the charts describe the draft in front of you — a position in your own launch sequence, not a result any campaign has produced.

Need more than a browser can check?

Launchpad handles the basics.
Ask us about the rest.

A few checks need a real sending server, a live inbox and somebody reading the replies — seed testing against the main providers, warming a fresh domain, verifying a list by hand, watching for replies. We can also run some of those for you, on a contracted sending platform with a licensed verification service, as part of a managed engagement. Describe your setup and we will confirm honestly what is possible.
