Most AI SDR tools sell personalization and skip the sending infrastructure underneath it. We build both: an agent that researches and qualifies leads against real signals, and the SPF, DKIM, DMARC, and warmup setup that decides whether any of it gets delivered at all.
An AI SDR agent built to actually reach inboxes
The problem, reframed
Gmail and Microsoft now reject non-compliant bulk mail outright at the SMTP level rather than quietly routing it to spam, and both providers weight actual recipient engagement; opens, replies, spam reports; over raw send volume. An AI SDR tool that writes great personalized copy on a domain with no DMARC alignment or a cold sending history still fails, because the message never reaches a human inbox to be judged on its content at all.
I think the AI SDR category oversells the writing part and undersells the plumbing part. Personalization quality matters less than most vendors claim once a domain's spam complaint rate crosses the threshold that gets it throttled. We build the agent and the sending infrastructure as one project, because shipping one without the other produces a system that looks good in a demo and fails in production within a few weeks.
What we build
01
Signal-based lead research and qualification.
The agent pulls from your CRM (HubSpot, Zoho, or Salesforce) plus enrichment sources to build outreach around real buying signals; a funding event, a job change, a specific tool in a prospect's stack; rather than firmographic mail-merge tokens like company size or industry that current spam filters pattern-match as generic at scale. Each lead gets a qualification score before it enters a sequence, not after.
02
Deliverability infrastructure, built first.
SPF, DKIM, and DMARC configured and aligned before a single outreach email sends, on a sending domain separated from your primary corporate domain so a deliverability problem never touches your main inbox reputation. Domain warmup runs on a gradual schedule that mimics real human sending patterns, because a sudden volume spike from a new domain is itself a spam signal.
03
Multi-channel sequencing.
Email through Postmark, SendGrid, Amazon SES, or your existing ESP, paired with WhatsApp Business API outreach where that channel fits the market, orchestrated through n8n so a reply on one channel updates the sequence state on every other channel instead of a prospect getting a follow-up email after they already replied on WhatsApp.
04
Compliance built into the send path, not bolted on.
One-click unsubscribe via the RFC 8058 header on every bulk message, spam complaint rate monitoring with an automatic pause if it approaches provider thresholds, and consent handling scoped to whichever of CAN-SPAM, UK PECR, or Canada's CASL applies to your target market.
05
Human handoff at the moments that matter.
The agent qualifies, personalizes, and sequences outreach on its own, but a reply indicating real buying intent routes to a human rep immediately rather than letting the agent attempt to close. We set the confidence threshold for that handoff based on your actual sales process, not a fixed default.
Recently shipped
Built for a B2B SaaS outbound program first. We scoped an AI SDR agent for a US-based SaaS team: signal-based qualification pulling from LinkedIn and funding data, personalized first-touch emails through a warmed sending domain with full SPF/DKIM/DMARC alignment, and human handoff on replies scoring above a calibrated intent threshold. The agent qualified 200-plus leads per week with a reply rate that stayed within Gmail's engagement benchmarks from day one because the infrastructure was built before the copy was.
Built on a modern, connected stack
Claude API and OpenAI handle the personalization and qualification logic, self-hosted n8n orchestrates the multi-channel sequencing and CRM sync, and Postgres with pgvector powers the lead enrichment retrieval when the agent needs to pull relevant account context before writing an outreach message. Every reply and qualification decision logs back to HubSpot, Zoho, or Salesforce automatically, so your CRM stays the single source of truth instead of a second system your reps have to check separately.
Who this is for
01
B2B SaaS companies
scaling outbound without hiring a full SDR team yet, who need volume without a domain reputation problem six weeks in.
02
Founders doing their own outbound
who need it systematized with real deliverability infrastructure instead of a personal Gmail account quietly getting flagged.
03
Companies whose current cold email tool is already struggling to land,
where the fix is the sending infrastructure underneath, not another personalization feature layered on top.
04
Agencies
wanting white-label AI SDR build capacity for client outbound programs, delivered with documentation their own team can maintain.
Why Flowagenz
Infrastructure and agent code you own outright.
Full ownership of the agent logic, sequencing configuration, and sending domain setup on completion. No recurring per-seat SaaS fee replacing a build you actually own.
Based in Salem, Tamil Nadu.
Western-grade engineering at a rate structure offshore delivery makes possible.
Real overlap, not vague promises.
Async-first communication with working hours that overlap US Eastern mornings, UK afternoons, and Australian business hours on the same day.
We build the unglamorous infrastructure most AI SDR vendors skip.
Domain warmup, DMARC alignment, and complaint rate monitoring are not exciting to demo, which is exactly why so many AI SDR products ship without them and fail once real volume hits a real inbox provider.
How it works
01
01
ICP, channel, and compliance scoping.
We confirm your ideal customer profile, which channels fit your market, and which compliance regime applies to your target geographies.
02
02
Deliverability infrastructure setup.
SPF, DKIM, DMARC, and a dedicated sending domain get configured and warmed on a gradual schedule, which typically runs in parallel with the agent build since warmup itself takes several weeks regardless of how fast the agent is ready.
03
03
Agent build.
Qualification logic, signal-based personalization, sequencing rules, and the human handoff threshold, tested against real leads from your pipeline before any live send.
04
04
Launch and tuning.
A monitored soft launch at low volume, complaint rate and reply rate tracked against the benchmarks for your market, with thresholds adjusted before scaling send volume up. Full engagements typically run 4 to 8 weeks, largely gated by the domain warmup timeline rather than the build itself.

FAQ
Frequently Asked Questions
Everything you need to know about our process and digital systems.
A typical AI SDR agent build runs INR 3,00,000 to 8,00,000 ($3,600 to $9,600) depending on the number of channels in scope, how many CRM and enrichment integrations are needed, and whether you need new sending domains warmed from scratch or existing infrastructure brought into compliance. A single-channel email agent with one CRM integration and a fresh sending domain sits at the lower end. A multi-channel agent with WhatsApp, multiple enrichment sources, complex qualification scoring, and recovery work on a damaged domain sits at the upper end. We scope on a call and quote in INR and USD together. The range above is honest for planning; your actual quote comes after the ICP, channel, and compliance scoping call.
