Cold Email Agency

Cold email campaigns that land, get read, and get replies

Fully managed cold email: dedicated warmed domains, verified lists, copy with a reason behind it, and reply handling. Deliverability handled end to end, so your messages reach inboxes — not spam folders.

What's included

Cold email is an infrastructure problem before it's a copy problem.

Anyone can write an email. Getting a thousand of them into inboxes is engineering.

Dedicated sending domains

We never send from your primary domain. Secondary domains are purchased, configured (SPF, DKIM, DMARC) and warmed for four weeks before launch — so your company's reputation is never at risk.

Verified, enriched lists

Every address is checked and re-checked before sending. High bounce rates kill deliverability; ours stay low because the list work is done properly.

Reason-led copywriting

Every message references why we're reaching out — a funding round, a hiring spree, an expansion. Short, plain-text, personalised. A/B tested continuously.

Reply & deliverability management

We monitor inbox placement daily, rotate sending patterns, and handle every reply — qualifying interest and converting the keen ones into meetings.

Process

From zero to inbox in four weeks

The warm-up period isn't a delay — it's the reason the campaign works in month two and beyond.

Set up infrastructure

Secondary domains, mailboxes, and authentication records configured on day one.

Warm for four weeks

Gradual, automated warm-up builds sender reputation before any prospect sees an email.

Build & verify the list

ICP-matched contacts gathered, cleaned and checked while the domains warm.

Write & test copy

Two to three angles drafted, approved by you, then A/B tested from launch.

Launch & optimise

Volumes ramp gradually. We watch replies and placement, and adjust weekly.

Book meetings

Interested replies are qualified, scheduled, and handed over with notes.

The maths

Cold email agency vs. hiring an SDR in Thailand

The honest comparison most agencies won't put on a page.

A capable SDR in Bangkok costs roughly ฿50,000–80,000 per month in salary before you add tools (sending platform, data, verification, enrichment — easily $300–500/month), management time, and a two-to-three-month ramp before the first meeting gets booked. And one SDR gives you one channel at one person's capacity.

A managed campaign starts at a comparable monthly cost, goes live in weeks, where an in-house hire takes months, and comes with the infrastructure and copywriting included, and can be cancelled anytime — no severance, no re-hiring cycle. If it doesn't work for your market, you find out cheaply and quickly. Many of our best-fit clients run LeadSire alongside an in-house closer: we fill the calendar, they close.

FAQ

Frequently asked questions

Will cold email damage our domain reputation?

No — because your domain never sends a single cold email. All outbound runs from dedicated secondary domains we set up and warm specifically for the campaign.

How many emails do you send per month?

Typically 3,000–8,000 depending on your plan and market size, ramped gradually. Volume without deliverability is worthless, so we scale only as inbox placement allows.

Is cold email legal in Thailand and abroad?

B2B cold email is lawful in most markets when done properly — accurate sender identity, a working opt-out, and relevant business context. We follow PDPA, GDPR and CAN-SPAM requirements as standard for the regions you target.

When will we see results?

First replies usually arrive within days of launch (week five overall, after the four-week warm-up). Meetings compound from there — cold email is a system that improves monthly, not a one-off blast.
