I do two things
Email deliverability and system administration. I'd rather be very good at two things than average at five.
Email Deliverability
Get to the inbox and stay there.
I set up your sending infrastructure and look after your domain reputation, so your mail lands where it should.
- SPF, DKIM & DMARC authentication
- Dedicated SMTP infrastructure
- IP & domain warm-up strategy
- Blacklist monitoring & removal
- Inbox placement testing
- Cold outreach & newsletter setup
System Administration
Servers that stay up.
I look after Linux servers and cloud infrastructure: setup, security, monitoring, backups, and documentation. When something breaks, it gets fixed fast.
- Linux server management
- Cloud infrastructure setup
- Security hardening
- Monitoring & alerting
- Backups & disaster recovery
- Zero-downtime migrations
When email lands in spam, nobody reads it
Most deliverability problems have ordinary causes: missing authentication records, a domain with a damaged reputation, or sending infrastructure that was never set up properly. None of it fixes itself.
I fix those causes directly: correct SPF, DKIM and DMARC records, your own SMTP infrastructure, a proper warm-up plan, and monitoring that catches reputation problems early.
Fix My DeliverabilityServers you don't have to think about
Most server problems trace back to the same thing: nobody fully owns the system. The last person left no notes, monitoring was never set up, and the backups were never tested. I take over that responsibility properly.
That means hardening, tested backups, monitoring with alerts, and written documentation for everything I touch. You keep full access at all times.
Take Over My ServersHow I Work
Every project follows the same four steps.
Audit
First I look at what's actually happening: authentication records, sender reputation, server configuration, logs. I don't guess.
Plan
Then you get a written plan: what's broken, what I'll change, how long it will take, and what it will cost. Nothing starts until you've agreed to it.
Fix
Then I do the work: infrastructure, authentication, monitoring, documentation. Changes go in step by step, so nothing that's already running breaks.
Monitor
Email and servers don't stay fixed on their own. Monitoring stays in place afterwards, so if something starts going wrong, we know before your customers do.
Rashedul Islam
Email Deliverability Expert | System Administrator
With over 10 years of experience, I specialize in email deliverability, helping businesses with cold email infrastructure and newsletter campaigns using custom SMTP servers to ensure maximum inbox placement.
The other half of my work is Linux system administration: cloud infrastructure, security hardening, monitoring, and migrations. The two go hand in hand: great deliverability is built on infrastructure you control, and I run both layers myself.
- You own your infrastructure, with no lock-in
- Written documentation for everything I set up
- Monitoring that spots problems before your customers notice

What Clients Say
A few words from people I've worked with.
“Our cold outreach was dying in spam and we couldn't figure out why. Rashedul audited the whole setup, rebuilt our sending infrastructure (dedicated SMTP, proper SPF/DKIM/DMARC, a sensible warm-up schedule) and walked us through every change so we could maintain it ourselves. Within a month we were landing in the primary inbox and reply rates nearly tripled. He's the first person I message when anything email-related comes up.”
Marcus Webber
Founder, B2B outreach agency
“Our store kept falling over on sale days. Rashedul moved us onto properly sized infrastructure with caching and real monitoring, and we haven't had an outage since, including our biggest campaign ever.”
Priya Sharma
E-commerce founder
“He migrated our servers with zero downtime and documented everything as he went. Six months later the infrastructure still hasn't needed a single emergency fix.”
Tomasz Kowalski
CTO, SaaS startup
“Our newsletter open rates collapsed after a domain blacklisting. Rashedul got us delisted, rebuilt our authentication from scratch, and set up monitoring so it can never happen silently again. Open rates recovered within three weeks.”
Elena Vasquez
Marketing director
“Fast, communicative, and the results showed up in our campaign metrics within weeks. We've hired him twice since and referred him to two of our own clients.”
James Whitfield
Agency owner
Frequently Asked Questions
Got questions? Here are answers to the most common ones.
I work in two areas: email deliverability (cold email infrastructure, custom SMTP servers, SPF/DKIM/DMARC authentication, warm-up, blacklist removal) and system administration (Linux servers, cloud infrastructure, security hardening, monitoring, backups, and migrations). If your email goes to spam or your servers give you trouble, that's the work I do every day.
Absolutely. I specialize in email deliverability optimization including cold email infrastructure setup, custom SMTP server configuration, domain authentication (SPF, DKIM, DMARC), IP warm-up strategies, and blacklist removal. I've helped dozens of businesses achieve inbox placement rates above 95%.
An audit takes a few days. Email deliverability setup typically takes 1–2 weeks including warm-up planning. Server builds and migrations take 1–3 weeks depending on complexity. I'll give you a concrete timeline after the audit, before any work begins.
Yes, that's a common starting point. I begin with an audit of what's running, document everything I find, and only then propose changes. You keep full ownership and access at all times; no lock-in, no black boxes.
Yes. Most clients keep me on a monitoring retainer after the initial project: server monitoring, deliverability checks, blacklist watch, and priority response when something needs attention. One-off projects are fine too.
Pricing depends on the project scope and requirements. I offer both project-based and retainer pricing. Contact me to discuss your specific needs and I'll provide a transparent, detailed quote.
