Deliveryman.ai automates the hardest parts of cold email infrastructure mailbox setup, DNS records, warmup, email verification, sending systems, blacklist monitoring, reply management, and routing. Instead of spending weeks setting up your own cold email infrastructure and fixing deliverability issues, you can launch faster, scale confidently, and focus on what actually drives revenue. No G-suite required. Warmup, email list verification, Blacklist monitoring, etc. all included in one tool.
Hey Product Hunt! 👋
We built deliveryman.ai because cold email infrastructure is absurdly broken.
Setting up a serious outbound system means juggling domains, configuring SPF/DKIM/DMARC, warming up dozens of mailboxes, monitoring sender reputation, and stitching together 4 different tools before you've sent a single email.
Deliveryman.ai automates all of that: Connect your domains, and we handle the technical setup, email warmup, lead list verifications, and ongoing deliverability management so your emails land in inboxes, not spam folders.
We're especially curious to hear from anyone doing high-volume outbound:
What's your current setup, and what breaks most often?
Drop it below. We read everything.

@junaidansari@aminmemon Congrats on the launch! I have been an early customer, but then the platform went into maintenance. Is it fully back now? Happy to resubscribe whenever my clients need it next. :)
@rohanrecommends Thank you, Rohan. Yes, we did pull the platform into maintenance to rebuild some core third-party pieces. We have built our own tech to eliminate such dependencies of controlling and customization when we scale email sending.
Traditionally, cold email teams buy domains, pay for Google Workspace mailboxes, subscribe to a warmup tool, use an email verification service, and then manage everything separately.
With Deliveryman AI, you don't need to buy Google Workspace mailboxes. Simply bring your domain name and connect it to Deliveryman AI. We'll automatically create and manage multiple mailboxes on your domain for your email outreach.
That means no Google Workspace subscriptions, fewer tools to manage, and significantly lower cost to send emails.

This would've saved me hours when I was building our outbound operation.
Can I use my existing domains or do I need new ones?
@aksayyed Thank you! That's exactly the kind of problem we built Deliveryman AI to solve.
Yes, you can use your existing domains.
In fact, established domains perform better than brand-new ones because they've had more time to build trust and reputation.
Simply connect your domain to Deliveryman AI, and we'll handle mailbox creation, warmup, monitoring, and the rest of the infrastructure for you.

Nice launch! Curious from a deliverability POV if a sending domain gets into trouble mid‑campaign, does @Deliveryman.ai auto‑failover to warmed backups, or do I need to step in and re-route things manually?
At this very moment, you will have to re-route things manually.
But, we will be building a simpler workflow in a couple of months that will make it possible with just a few clicks.
Normally, users don't keep their domains idle. All connected domains keep running campaigns all the time.
Maybe once the development of this new process is live, we can provide you with an option to auto add backup domains if the current domain gets into trouble.
Awesome that you unify DNS, warmup, verification, blacklists. How do you stop the system from over-warming dormant domains, and what’s your playbook when a mailbox health score drops suddenly?
@leventbuilds Thank you. Happy to know that you found our product useful. Great question.
For warmup, we gradually increase sending activity rather than aggressively ramping up volume. We also coordinate warmup behavior with actual campaign activity so mailboxes aren't unnecessarily overworked when they're already sending outreach.
As for mailbox or domain health, that's honestly one of the hardest problems in deliverability. Every email provider behaves differently, and there isn't a single reliable "health score" source. We've integrated with Google Postmaster to gather insights, but the data isn't always comprehensive or updated frequently. In fact, newer versions of Postmaster no longer expose some of the domain reputation signals that were previously available.
Rather than showing a fancy score that may not reflect reality, we're actively working on ways to combine multiple signals and build a more accurate picture of deliverability health. It's an area we're continuing to invest heavily in.
Curious though - so this is handling the mailbox + warming up domain emails and then I will bring the leads list from say Apollo? Or that is handled as well?
And how are you making sure that my emails will still not go to spam?
Yes, that's correct. Creating & handling the mailbox + warming up domain emails (+ verifying lead list emails + monitoring popular blacklists) is all taken care by Deliveryman AI.
Deliveryman AI handles the infrastructure side of cold email of domains, mailboxes, DNS setup, warmup, email verification, blacklist monitoring, and inbox management. You can bring your leads from Apollo or any other lead source and use your preferred sending workflow.
As for spam prevention, no platform can guarantee that emails will never land in spam. Deliverability depends on several factors including infrastructure quality, list quality, email content, sending behavior, domain age, and recipient engagement. Our motive is to give you the healthiest possible foundation by automating the technical side and following deliverability best practices, but campaign quality still plays a huge role.
Out of curiosity, what's your current outbound stack today?
Follow-up question, what if I buy a domain and I just want the mailbox + warmup? Is that a tier you offer?
Report
Cool! We currently use 5 separate services for this.
Does it provide recommendations as well? For example, if you get added to a blacklist, does the service automatically suggest best-practice actions, such as stopping email campaigns for 30 days?
@natalia_iankovych Thanks! That's exactly the problem we're trying to solve.
Most teams end up stitching together multiple tools just to manage their email infrastructure.
When a domain is detected on a blacklist, Deliveryman.ai automatically pauses email campaigns when necessary (depending on the severity of the blacklist) to help protect your sender reputation.
We also provide step-by-step guides for removing domains from the relevant blacklists. Once the issue is resolved and the domain is delisted, you can safely resume your campaigns.
Our goal is to not only monitor deliverability issues but also help users take the right actions to recover quickly and keep their outreach running smoothly.
Out of curiosity, which 5 tools are you currently using to manage your email infrastructure?
@junaidansari Congrats on the launch! How does the warmup handle domains that go quiet for 30+ days mid-campaign (paused outreach, seasonal gaps)? Do you ramp them back up automatically or treat them as fresh?
With Deliveryman AI, domains don't really go "cold" when you're not actively running campaigns.
We continuously balance campaign sending volume and warmup activity. As your campaign volume decreases, warmup volume automatically increases to maintain healthy sending patterns and positive engagement signals. When you resume sending campaigns, warmup volume is adjusted back down accordingly.
This helps ensure your domain maintains a consistent reputation with email providers, even during seasonal gaps or periods of low activity.
We also factor in metrics such as bounce rates, inbox health, and overall sending performance to dynamically adjust warmup behavior over time.
The result is that your domain remains healthy and ready to send, without needing to be treated as a fresh domain after a period of inactivity.
How are you currently handling warmup for domains when campaigns are paused for a few weeks or months?
Report
@junaidansari That's a more thoughtful approach than I expected - most tools treat warmup as a one-time ramp rather than a continuous balancing act. For your question: currently in early distribution mode, so handling it manually and at low volume, but the dynamic adjustment you're describing is exactly the kind of thing that breaks quietly without it.
