What exactly does "cold email infrastructure" include?
All the technical components needed for successful outreach: dedicated servers, IP addresses, domain configuration, authentication (SPF, DKIM, DMARC, BIMI), email account setup and deliverability optimization. We handle the entire setup so your emails reach the inbox reliably.
Can you build software for my type of business?
Yes. We custom-build CRM and POS systems for retail shops, supermarkets, hotels, restaurants, bakeries, clinics, schools, real estate, service companies, distributors and more. If your business has a process, we can build software around it.
What is a customized CRM, and how is it different from HubSpot or Zoho?
Ready-made CRMs give every business the same screens. We build a CRM around your own stages, roles, documents and reports, so your team works the way it already does, without paying for features you never use.
Can you move our existing data into the new CRM?
Yes. We migrate customer lists, leads, products and history from Excel sheets, CSV exports or your current software as part of the build.
Will the CRM work with our email campaigns?
Yes. Replies and engagement from your cold email infrastructure can flow straight into the CRM pipeline, so no lead gets lost between tools.
Is your WhatsApp bulk messaging safe for my number?
Yes. We use the official WhatsApp Business API, not unofficial tools that get numbers banned. Messages go only to customers who have opted in, and opt-outs are handled automatically to keep your quality rating high.
Do WhatsApp templates need approval?
Yes. Any message you start (a broadcast, reminder or offer) must use a template approved by Meta. We design your templates, submit them and track approval for you, usually within a short time.
How much does WhatsApp messaging cost?
Meta charges per template message based on the template category (Marketing, Utility or Authentication) and the customer's country. Replies inside an open customer conversation are free of Meta charges. We share a clear cost estimate along with your plan.
How many emails can I send with your infrastructure?
From thousands to millions monthly, depending on your setup. We create custom configurations based on your volume needs while keeping deliverability high.
Will your system work with my existing CRM or sales tools?
Yes. We have integrated with HubSpot, Salesforce, Pipedrive and many others. If you use a specific tool, we can discuss integration during your consultation.
How long does setup take?
Basic email infrastructure is typically ready within 2–3 hours; complex or high-volume setups can take 12–24 hours, followed by a 4–8 week warm-up. CRM timelines depend on scope and are agreed after workflow mapping.
Do you provide ongoing support after setup?
Absolutely. Our maintenance plans cover deliverability monitoring, technical adjustments, CRM updates and best-practice guidance.
How does your pricing work?
Pricing depends on the scale and complexity of what you need. Email plans include setup, authentication and initial warm-up; CRM projects are quoted after the discovery call. Contact us for a personalized quote.
