DELIVERABILITY GATE
Every send is checked against your live deliverability first. If your score slips, sending pauses until it recovers. Your domain stays clean.
01 / THE PROBLEM
Your cold email is going to spam.
In 2026 it is usually not your copy. Google, Yahoo and Microsoft now reject unauthenticated bulk mail outright. These are the real causes.
Broken authentication
SPF, DKIM and DMARC are mandatory now. If any of them fail, the big providers drop your mail before a human ever sees it.
Zero reputation
A fresh inbox has no sending history. Mailbox providers treat it as a stranger, and strangers sending in bulk go straight to spam.
Sending too fast
Blasting 200 emails on day one from a new inbox is the fastest way to burn a domain. Providers read volume spikes as spam behaviour.
Dead addresses
Bounce rate needs to stay under roughly 2 to 3 percent. An unverified list blows past that and drags your reputation down with it.
02 / THE FIX
How Conductor fixes it.
One machine, end to end. You connect an inbox and it handles everything between you and the reply.
Connect your inbox
Sign in with your Google or Microsoft account. That is the whole setup.
We fix your deliverability
We find what is broken in your SPF, DKIM and DMARC and fix it in one click.
We warm it up automatically
Your inbox builds real sending reputation before a single cold email goes out.
Import your list, we verify it
Dead and risky addresses are removed so your bounce rate stays under the limit.
Launch a sequence
Sent slowly through your own inbox, and gated on live deliverability the whole way.
Watch replies land
Replies come straight back to your inbox. You just answer them.
03 / AFTER THE REPLY
What happens after they reply.
Most tools stop at the send. Conductor reads every reply that comes back, sorts it, and gets the next step ready before you open your inbox.
Noise handled for you
Bounces and out-of-office autoresponders are detected and handled automatically. Bounces feed the circuit breaker, out-of-office pushes the next step back. You never see them.
Only real replies reach you
Every reply is classified: positive, negative, or a question. Your inbox shows real humans only, so nothing worth answering gets buried.
Pauses the moment they say yes
A positive reply pauses that contact's sequence instantly. No awkward follow-up landing after someone already said they are interested.
Confirmation drafted, you click send
For every positive reply, Conductor drafts a short confirmation with your booking link, threaded into the conversation. Review it and send with one click.
04 / WHY CONDUCTOR
The closed loop.
- ✕ Send, and only send. Deliverability is your problem
- ✕ Assume your authentication is already set up correctly
- ✕ Keep sending at full speed while your reputation slides
- ✕ You find out from bounce reports, after the damage is done
- ✓ Fixes your deliverability before anything sends
- ✓ Warms up first, then paces every send conservatively
- ✓ Checks live deliverability before each send, and pauses when it slips
- ✓ Built so you never burn your domain to hit a quota
Other tools send. They do not fix your deliverability first, or stop sending when it slips. Conductor does both.
