Cold Email Infrastructure for Durban Agencies — 10K Emails/Day Without Landing in Spam
Custom domains, warm-up, deliverability monitoring — everything you need to scale outbound.
From Umhlanga corporate parks to Morningside medical practices, Ballito tourism to Pinetown logistics.
Why Durban businesses are switching to Cold Email Setup
Generic cold email from your main domain gets you flagged as spam within 100 sends. Most SA agencies burn their domain reputation within weeks and can't understand why outbound stopped working.
Durban clinics and tourism businesses see huge demand spikes around school holidays. AI handles the surge without the cost of seasonal hiring.

About Durban — and why this matters for local businesses
Durban's economy mixes tourism, port logistics, and a growing tech sector in Umhlanga. The relaxed coastal business culture means many clinics and service firms operate with small teams — automation is the only realistic way to handle peak demand (December holidays, conference season) without hiring seasonal staff.

Questions from Durban business owners
How many emails can I send per day without getting flagged?
With proper warm-up and rotation, we typically enable 10,000–25,000 sends per day across 10 warmed domains. Volume per inbox stays at 30–50/day during warm-up (weeks 1–6), then ramps to 150–200/day in production.
What's the warm-up period?
For new domains registered now: 4–6 weeks of warm-up before production sends. For Durban agencies needing to move faster, we can supply pre-warmed domains (30+ day reputation) at a higher starting price.
Which cold email platform do you use?
We work with whatever you prefer: Instantly.ai (our most common choice — reliable + good pricing), Smartlead (better for multi-account agencies), or Lemlist (strongest copy features). We set up and configure whichever one fits your use case.
