SyncMaster runs your own fleet of sending servers, grades each one's reputation every day, and mails your list on schedule. You own the servers, the domains, and the data. No platform can freeze your account.
Most vendors run three or four commercial autoresponders at once. Not by choice. When one starts landing in spam, the others can still reach the inbox while it recovers. It's expensive, slow to operate, and every account can ban you without warning.
SyncMaster replaces that stack with a fleet of small SMTP servers that you own. The app provisions them, warms them, sends through them, and grades them. When a server's numbers slip, it pulls that server out and rebuilds its reputation while the rest keep mailing. Your list lives in your database, not on a vendor's platform.
The cost model flips too. Commercial autoresponders bill by list size, so growth is a tax. Here you pay for servers, roughly a few dollars each per month. A 500k list costs the same to hold as a 50k one, and dead subscribers cost nothing to keep.
You follow a step-by-step playbook: it tells you exactly where to open each account and which settings to use. From there it's automated. SyncMaster handles the provisioning, the sending, and the reputation work.
Connect your VPS accounts and your registrar. The app provisions small sending servers, each with its own IP and domain, and publishes SPF, DKIM, and DMARC for every one. Each server warms up on a ramp instead of blasting from cold.
Sends spread across the day in 288 windows rather than one burst that trips filters. Each server is capped near 4,000 messages a day to stay under Google's 5,000-to-Gmail bulk-sender line. That cap isn't a ceiling on your returns: a server costs about $5 a month and still sends enough to pull thousands of clicks, so you scale by adding cheap servers, not by paying more per subscriber. Every subscriber is routed by how recently they opened: hot, warm, or cold.
Every day each server is scored on opens, bounces, and complaints against its peers and its own baseline. Every 2 hours the app pulls Google Postmaster reputation directly. A server going bad is quarantined and rebuilt on its own. The rest carry the volume.
Hosted opt-in and bridge pages capture leads, validate them, and drop them straight into the fleet. Clicks run through your own branded domains with fraud scoring. The app writes email copy, tests it by real click-through, keeps the winners, and retires the rest.
Once it's set up, your only job is bringing new leads. Fleet setup, warmup, sending, copy, and reputation all run on their own.
Sending, list hygiene, click tracking, opt-in capture, and compliance in one place. Grounded in what runs today, not a roadmap.
Daily scoring promotes, demotes, and quarantines servers on their own numbers. No babysitting.
Google reputation, spam rate, and auth pass rates read every two hours and shown on a dashboard.
Hourly DNSBL checks plus Spamhaus delisting tracking, with alerts when an IP or domain gets listed.
Apple Mail Privacy and prefetch traffic filtered out, so opens reflect people, not proxies.
Validation suppresses traps and bad addresses. Sunset and re-engagement sweeps stop you mailing the dead.
Clicks run on your own domains with per-click fraud scoring and per-source attribution.
See which traffic vendors send real clickers and which sell bots, broken out by source.
Copy is generated, sent, and ranked by click-through. Winners stay in rotation, losers get pulled.
Nine hosted templates with a live editor, your tracking scripts, and post-optin redirects.
SPF, DKIM, DMARC, and one-click unsubscribe set up per domain to meet the Google and Yahoo rules.
One bad server can't take you down. Volume reroutes across the fleet while it recovers.
Send rates tighten on their own when bounces climb at a given mailbox provider.
Before this was an offer, it was the system I ran my own sends on. Solo-ad traffic is dirty by nature: recycled addresses, low engagement, the occasional trap. That's the exact condition it was built to survive, and these numbers come from running it on that, not on a clean opt-in list.

No tiers, no per-subscriber fees. The same price whether your list is 50k or 2M. Self-install at no setup cost, or add white-glove setup and I wire the whole thing up for you. You bring your own VPS and domains either way, a few dollars per server per month.
The full platform, the hosted click edge, and updates. Your servers, your list, your data.
flat, any list size · self-install at no setup cost
Most people self-install for free. Take this only if you'd rather hand me the keys and have it all set up for you.
standard setup · very large fleets and dirty lists quoted separately
What you pay on top: your VPS servers and domains go on your own accounts (roughly $5 per server per month, plus domain registration), and a fleet at that cost pays for itself fast against the clicks it pulls. Validation runs about $0.004 to $0.01 per email, yours at cost. No subscriber-count surcharge. Total it against three or four autoresponders plus a validation tool plus a click tracker, and the math usually lands in your favor.
Two ways in. Self-install comes with a step-by-step playbook that tells you exactly where to open each account, which settings and warmup numbers to use, and what to run, so it's follow-the-guide rather than figure-it-out. If you'd rather skip it entirely, the white-glove setup add-on covers all of it: you create the accounts, hand me the keys, and I wire the whole thing up. Either way, once it's live the fleet runs itself and your only job is bringing new leads.
Yours. You create the VPS accounts and the domain registrar account, and SyncMaster provisions the fleet inside them. That's the whole point: the sending reputation, the IPs, and the list all belong to you, not to a platform that can switch you off.
Fair concern, so here's the straight answer: VPS hosts suspend accounts over spam complaints, which is the exact thing this is built to prevent. It validates your list, suppresses traps, and pulls any server whose complaints climb before a host ever notices. And because you run a fleet instead of one account, no single host's decision takes your whole list down the way an ESP ban does. The risk shifts from "one company can end you overnight" to "one cheap server gets replaced".
That's the exact problem it's built for. Dirty traffic torches IPs when you mail all of it equally and find out too late. Here, every import is validated and traps are suppressed before the first send. Subscribers are routed by how recently they engaged, so your freshest servers only touch your best addresses. Any server whose bounces or complaints climb gets pulled and rebuilt on its own, before it drags the rest of the fleet down. It doesn't assume your list is clean. It sends as if it isn't.
For broadcast sending to a list, yes. It handles the sending throughout the day, the reputation management, suppression, click tracking, and opt-in capture. What it does not do yet is visual drip sequences with branching and wait steps. If your business depends on long automated follow-up funnels, keep that in mind.
Yes. Lists import by CSV, and the app can validate them on the way in to drop traps and bad addresses before the first send. If you take the white-glove setup, I run the migration and the warmup so you don't torch a cold fleet by mailing a big list on day one.
Not on day one, and that's deliberate. Every new server, IP, and domain has to warm up. Each one starts at a low daily cap and climbs on a ramp over a few weeks. Cold infrastructure that blasts at full volume gets filtered and burns the reputation you're trying to build, which is the whole problem this is meant to solve. If you take the white-glove setup, I run that warmup for you; either way the app paces the ramp on its own. Plan for it: reaching full fleet volume takes weeks, not an overnight switch.
No, and you shouldn't. Because new servers warm up over a few weeks, the right move is to run this alongside your current autoresponders and move volume across as the fleet earns its reputation. You double-run for a short stretch, then cut the old stack once you're inboxing at full volume. The playbook walks you through the handover so you never drop sends in the middle.
The daily grader catches it from the open, bounce, and complaint numbers, and Google Postmaster reputation confirms it. The server gets pulled out of normal rotation and put into recovery, where it only mails your most engaged subscribers until its numbers come back. The rest of the fleet absorbs the volume, so your sending doesn't stop while one box heals.
That's built in. Every sending domain gets SPF, DKIM, and DMARC on provisioning, every message carries a one-click unsubscribe header, and the app holds your complaint rate under the line that gets senders throttled. Staying compliant is most of what keeps deliverability stable, so it isn't an afterthought here.
Your own infrastructure. A VPS server runs about $5 a month and sends enough to pull thousands of clicks a month, so the return per server is easy to see. You scale by adding servers as you send more, not by paying more as your list grows. Domains are a normal registration cost. Email validation is metered, roughly $0.004 to $0.01 per address, billed to you at cost. There is no per-subscriber fee at any point.
Month to month, cancel anytime. Two things to know up front. Your list, your servers, and your data are yours to keep and export at any point, and the app keeps running on your own infrastructure. Branded click tracking, though, runs through hosted infrastructure I operate, so it's part of an active subscription rather than something that keeps serving after you stop paying. If you ever want to take click tracking in-house, we can arrange a handoff.
Bring your accounts and your list. I'll do the rest, or hand you the keys to run it yourself.
