Real Friction Points

HubSpot
HubSpot Marketing Hub costs $800/mo at 2,000 contacts and $3,600/mo at 10,000 contacts; one Engagebay-documented user reported paying $21,600/yr ($1,800/mo) for 20K contacts plus $800/mo Marketing Hub and $400/mo Sales Hub — a total that balloons from the $15/mo starter price advertised. Going over a tier limit by a single contact auto-bumps your subscription to the next tier, and Professional/Enterprise plans require annual commitments with no refunds on early termination. G2 reviewers also flag a clunky landing page builder, buggy UI, pushy sales team, and a broken booking system as recurring mid-market pain points.
Klaviyo
Klaviyo pricing scales roughly 20× from 500 to 25,000 contacts ($20/mo → ~$400/mo), and the February 2025 shift to 'active profile' billing means unsubscribed contacts still count toward your bill per sender.net analysis. There is no phone support — live chat routinely refers users to self-help docs, and one G2 reviewer documented emailing success@klaviyo.com 14 times with zero response while trying to scale up usage. A 25% price-increase cap applies to existing customers post-2025, and SMS costs are metered on top of the already-inflated Email+SMS plan tiers.
The Verdict
Choose HubSpot if you need the CRM + marketing + sales stack in one platform and can stomach the $2K+/mo ceiling at 20K contacts — the integrated suite genuinely replaces 3-4 point tools. Choose Klaviyo if you're e-commerce-first and revenue-per-email is your north star; you'll save 4-6× monthly while getting better attribution, at the cost of needing a separate CRM for sales ops.
