The short version

Each has a real cost: Postmark free tier caps at 100 emails per month with no overages allowed; WebEngage nothing about pricing is published, and since the entire commercial argument for WebEngage is that it undercuts Braze and CleverTap, you cannot evaluate the one thing that makes it interesting without entering a sales process.

WebEngage

A consumer app in India or Southeast Asia with several million monthly users needs Braze-class journey automation at a price its marketing budget can absorb.not Postmark
A fintech or edtech business needs WhatsApp as a primary retention channel rather than a secondary one, in a market where email open rates are low and WhatsApp is universal.not Postmark
A media or ecommerce company wants behavioural segmentation and lifecycle journeys without building a customer data platform separately first.not Postmark
A team wants funnels, cohorts and retention analysis in the same tool that sends the messages, so the analyst and the campaign manager are not reconciling two systems.not Postmark

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Postmark

Free tier caps at 100 emails per month with no overages allowed
Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume
Custom high-volume pricing above the published tiers requires contacting sales

WebEngage

Nothing about pricing is published, and since the entire commercial argument for WebEngage is that it undercuts Braze and CleverTap, you cannot evaluate the one thing that makes it interesting without entering a sales process.
Message volumes across email, SMS and WhatsApp are metered separately from the platform fee, so a campaign that succeeds increases the bill in ways the monthly tracked user figure does not capture.
It requires genuine engineering investment to instrument events and user attributes correctly, and a poorly instrumented deployment produces segments that are wrong rather than merely incomplete, which is expensive to discover after launch.
Enterprise assurance is lighter than the American incumbents: procurement teams expecting extensive compliance documentation, regional data residency guarantees and 24 hour follow-the-sun support may find gaps.
Its centre of gravity is India, Southeast Asia and the Middle East, so partner availability, agency expertise and support hours all favour those regions and a European or North American buyer is a peripheral customer.
