Sendable Deliverability auditor
Changelog

Updates: what we shipped.

Sendable is in active beta, and we ship almost every day, sometimes a quick fix, sometimes something big. Every change, newest first.

v0.45.0 Latest
Forwarded emails get a fair score

When you forward an email to check it, forwarding scrambles the sender's fingerprints and used to drag the score down to almost nothing. Now the app spots a forward, grades the real email inside it, and sets aside the checks that forwarding breaks, so you see a true score.

ImprovedAudits
  • Forwards graded fairly. A forwarded email no longer scores near zero. We pull out the original email and skip the checks that forwarding rewrites.
  • Nothing hidden. The set-aside checks still show, marked as skipped because it's a forward, so you always see the full picture.

v0.44.0
Domain Health knows who's really sending as you

Your DMARC dashboard got a lot better at recognizing senders. It stops flagging your own providers and email security scanners as impostors, groups a sender's many servers into one, and only raises an alarm when there's a real, recurring problem.

ImprovedDomain Health
  • Fewer false alarms. Your own providers, like Microsoft, and security scanners are now recognized instead of showing up as unknown impostors.
  • Real threats stand out. Only unrecognized sources with no history are flagged as spoofing, and a trusted sender's one-off hiccup stays quiet.
  • Smarter escalation. A sender that keeps failing gets flagged as a pattern worth fixing, not a single scary blip.
  • Clearer logo setup. When your policy is strict enough to earn a brand logo (BIMI), we now show the exact record to add.

v0.43.2
Easier to find us by name

We made it clearer to search engines that "sndbl" means Sendable, and kept our app's sign-in pages out of search results, so looking us up by name brings up the homepage instead of the login screen.

ImprovedDiscoverability
  • Brand name recognized. Searching "sndbl" now points to the homepage, because search engines know the domain and the brand are the same thing.
  • Cleaner search results. The app's sign-in and internal pages no longer show up in search, so people land on the right page.

v0.43.1
Live numbers on the homepage

The headline stats on the homepage now come straight from the product, the founders using Sendable, emails audited, and domain reports processed, and they roll up from zero as you arrive instead of sitting as fixed numbers.

ImprovedHomepage
  • Real, live counts. The three proof numbers now update on their own, so they always reflect what's really happening.
  • Count-up animation. Each number rolls up from zero as the section scrolls into view.

v0.43
Easier to find on Google and AI search

We made the Sendable site properly discoverable, so our free tools and guides turn up when you search for help with email deliverability, whether that's on Google or through an AI assistant.

ImprovedDiscoverability
  • Search engine ready. Added a sitemap, tidy page descriptions, and rich metadata so Google and Bing can index every page and guide.
  • AI answer ready. The site now welcomes AI assistants and describes itself for them, so tools like ChatGPT and Perplexity can find and cite our guides.

v0.42
A friendlier free checker and a smoother way in

We made the free domain checker more honest, steadied up audits and drafting, and made requesting beta access a lot simpler.

NewGetting started
  • Request beta right from a domain check. After the free checker shows your result, you can ask for beta access to get a daily report on that domain, with your email carried straight into the request form.
  • Quick questions on the request form. The beta request now asks how you heard about us and your role, so we can get you set up faster.
ImprovedFree domain checker
  • No more false alarms. When we can't scan your DKIM (for example a custom Amazon SES setup) or your DMARC is still in monitoring mode, we now show it as neutral instead of a scary red issue, because it isn't actually a problem.
ImprovedAudits and drafting
  • Steadier verdicts. Audit scores stopped flip-flopping between runs, now settled by a majority vote across checks.
  • Smarter rewrites. Regenerating a draft now learns from the version you rejected and checks itself against your audit as it writes.
  • Reads more pages. Audits can now open links that sit behind bot protection, so fewer come back blank.
ImprovedSign in
  • Clearer Google permissions. The sign-in page now explains, in plain English, exactly what Google access Sendable asks for and why.

v0.41
Domain Health opens about 10× faster

Domain Health used to pause for around ten seconds before showing anything. Now it opens in under a second, and stays that quick however many reports you've built up.

ImprovedSpeed
  • ~10× faster Domain Health. We now do the heavy lifting the moment your reports arrive, instead of redoing it every time you open the page, so it loads straight from your latest check.
  • Stays fast as you grow. Months of report history no longer drag the page down.
NewGetting started
  • A welcome email when you're approved. The moment we let you into the beta, you'll get an email letting you know you're in, so you don't have to keep checking the sign-in page.
June 19, 2026
v0.40
Ask for access, right from sign-in

Not in the beta yet? Request access in one step from the sign-in page, and we'll let you know the moment you're approved.

NewGetting started
  • Request-access form on the sign-in page, so new people can put their hand up without emailing anyone.
  • We review every request and approve you for the beta from there.
June 18, 2026
v0.39
Know exactly who's sending as you

Mystery sending servers now show a real name, and the sender the verdict warns about always turns up in the list right below it.

NewDomain Health
  • Real names for unknown senders. An anonymous “Unknown source 175.x.x.x” now resolves to the actual server name, so you can tell at a glance whose it is.
ImprovedDomain Health
  • The top warning always matches the list. A source the headline verdict flags now appears in the senders list below it, instead of an alarm you couldn't click into.
June 17, 2026
v0.38
Fairer scores for everyday inboxes

Sending from a personal mailbox like Gmail or Outlook no longer drags your score down for setup you don't control.

ChangedAudits
  • Personal-mailbox sends are scored on what you can change (your subject, content and links) instead of being penalised for how Gmail or Outlook signs your mail.
ImprovedAudits
  • Audits you ran before the change were re-scored automatically, so your history reflects the fairer numbers too.
June 13, 2026
v0.37
Domain Health, hands-off

Point your domain's reports at us once and Domain Health runs itself: who's sending as you, impersonators flagged first, re-checked every single day.

NewDomain Health
  • Your own Domain Health dashboard: one plain verdict, everyone sending under your name, and exactly what (if anything) needs doing.
  • Re-checks itself every day. The picture is never stale, with nothing for you to remember to run.
ImprovedDomain Health
  • Threats first. Anything blocked or unrecognized is promoted to the top; the routine, healthy stuff tucks away.
  • One-paste fixes. When a genuine tool can't send as you, we hand you a ready-to-paste record to drop straight into your domain settings.
FixedDomain Health
  • The health colour now always matches the real verdict.
  • Domain pages load instantly from your latest check instead of stalling on a fresh scan.
June 10, 2026
v0.36
Faster everywhere, and a clearer to-do list

Dashboards load noticeably quicker, and your domain issues now arrive as a ranked, plain-language worklist.

ImprovedSpeed
  • No more blank-then-pop. Heavy pages now open with their data already in place.
  • Loading placeholders and lighter background refreshes across the whole app.
NewDomain Health
  • Ranked worklist. Findings sort into a clear order with a tier and at-a-glance chips, so you fix what matters first.

v0.35
Say hello to Sendable

We renamed the app to Sendable and made it far friendlier to land in for the first time.

ChangedBrand & navigation
  • InboxHealth is now Sendable across the whole app.
  • Plain-language navigation, and the Voice tab is now Brand Voice.
NewGetting started
  • A short welcome tour walks you through the app the first time you sign in.
  • A new user menu in the corner, with a proper “are you sure?” sign-out.
ImprovedGenerate
  • A 3-step guided flow, with the brief and the writing controls clearly separated.
June 4, 2026
v0.34
Generate gets smarter

Feed Generate more than text. Paste links or drop in files and it folds them into your draft.

NewGenerate
  • Paste up to 3 links and we read each page into your brief automatically.
  • Attach a file (PDF, Word, or plain text) and we pull the details straight in.
ImprovedGenerate
  • The brief now resets cleanly after each draft.
June 1, 2026
v0.33
Audits you can act on

The audit report became a fix-first worklist instead of a wall of detail.

NewAudits
  • Fix-first report showing the real points you'd gain from each change.
  • Tap a category chip to filter the report down to what's hurting that score.
NewDashboard
  • A get-set-up checklist and a plain first-run state, so new users always know the next step.
May 27, 2026
v0.31
Hello, beta

The first build real people could use: audit a send, see who's emailing as your domain, and turn rough notes into a draft.

NewAudits
  • The core audit: a score out of 100 with the issues most likely to keep an email out of the inbox, from mail sent to your +audit alias.
NewDomain Health
  • A first domain dashboard: a verdict, key metrics, and who's sending as you, powered by your domain's own reports.
NewGenerate
  • Paste-a-brief: drop in a paragraph and we turn it into ready-to-edit brief fields.
NewGetting started
  • A guided setup wizard to get you connected in a couple of minutes.

v0.1
Where it began

The first private build, weeks before the beta: the deliverability audit engine, a secure Gmail connection, and the pipeline everything since is built on.

NewFoundations
  • The audit engine — the deliverability and copywriting scoring that powers every report today.
  • Sign in with Google, so each account connects its own inbox securely.
  • An ingestion pipeline that reads each send once and never double-counts it.
