The two-cost reality
Most vendors show you the platform cost. The build cost where actual value is created is the investment that determines whether the platform delivers return.
Layer 1: Platform subscription costs (2026)
| Platform | Free tier | India pricing |
|---|---|---|
| HubSpot | 500 contacts | Dollar pricing |
| Zoho Campaigns | 2,000 contacts | Rupee pricing |
| Klaviyo | 500 contacts | Dollar pricing |
| ConvertKit | 10,000 subscribers | Dollar pricing |
| Mailchimp | 500 contacts | Dollar pricing |
For a Mumbai SMB with 1,000 2,000 contacts: the monthly platform cost is accessible on any of these. The cost scales with list size plan for 6-month and 12-month cost, not just the starting tier.

Build cost covers: workflow architecture design, email copywriting (25 40 emails for a 6-workflow system), technical configuration and testing, deliverability setup (SPF, DKIM, DMARC, domain warming), and integrations (CRM, e-commerce, WhatsApp BSP, website forms).
Starting-from ranges at Perceptra:
A starter build (2 workflows, basic segmentation): lower project fee. Standard (5 workflows, CRM integration, multi-channel): mid fee. Full e-commerce system (Klaviyo + Shopify, cart recovery + post-purchase + browse abandonment): scoped project fee. Every project receives a fixed written quote before work begins.

What drives build cost higher
More workflows: Each additional workflow is design + copy + configuration. E-commerce integrations: Shopify/WooCommerce to Klaviyo requires careful event mapping. WhatsApp integration: Adding WhatsApp alongside email doubles channel complexity. Deliverability remediation: A domain with a poor sending reputation needs fixing before launch.
The ROI frame
A list of 2,000 contacts with a working abandoned cart sequence (recovering 7% of carts at ?1,200 AOV) and a welcome sequence (converting 5% to a discovery call) generates measurable incremental revenue every month from subscribers you already have. Most well-built systems pay back their build cost within 60 120 days.
Frequently asked questions
Can we do everything ourselves using free tools? Yes with 4 6 weeks of setup and learning. Your time has a cost that often exceeds the build fee at most reasonable valuations of what your time is worth.
Is there a minimum list size for the investment to make sense? 500 engaged contacts is the practical minimum. Below that, focus on growing the list before automating it.
Does platform cost include email delivery? Yes delivery is included in platform subscriptions. WhatsApp delivery incurs additional Meta conversation charges separately.
