Unlayer vs Stripo Plugin: flat platform pricing against per-template metering

The comparison is an arithmetic problem

Both products embed a white-label drag-and-drop email builder in your application. Both maintain mail-client compatibility. Both support merge tags and AI assistance. The editors are comparable enough that a feature-by-feature reading will not separate them.

What separates them is what you are charged for.

Model your own numbers first

Stripo charges by unique emails created per month: $100 for 400, $550 for 15,000. If your product has 200 customers who each maintain two templates and edit them occasionally, you are at the bottom of that curve and paying very little.

Unlayer charges a platform fee: $250 per month at Launch, $750 at Scale. Template volume does not change it. If your customers create templates constantly — an agency platform, a high-churn newsletter tool — that predictability is worth the higher entry.

The crossover is somewhere between those two shapes, and only your own numbers locate it. Build the spreadsheet before reading either vendor's comparison page, including this one.

Where Unlayer wins beyond price

• Landing pages as well as email, from one integration.
• On-premise deployment under enterprise terms, where Stripo is hosted only.
• A widely used React wrapper, published since 2017, with a large body of public integration experience.
• Predictable billing, which finance teams weigh more heavily than engineers expect.

Where Stripo wins beyond price

• AMP and interactive email modules, which fewer competitors support properly.
• A lower floor: $100 per month is reachable for a product still finding its market.
• A large template catalogue included.
• Metering that rewards controlled usage, which suits vertical SaaS with a stable customer base.

The verification difference

One structural note that belongs in an evaluation: Unlayer publishes an npm package we could verify against the registry, with a licence, publication history and current version. Stripo Plugin has no public package or repository we could check, so several fields in our dataset stay null for it.

That is not a product judgement. It does mean that if machine-verifiable vendor information matters to your procurement, one of these two gives you more of it.

Migration

Exported HTML is portable from both. Editable templates are not: each vendor's design format is its own, and moving means re-creating templates.

For platforms with customer-created templates at scale, negotiate an export path before signing. Neither vendor's standard terms solve this for you.

Verdict

Low, stable template volume: Stripo, and confirm the "unique email" definition in writing. High or unpredictable volume, or a need for landing pages and a self-hosting story: Unlayer.

If both entry prices are too high, Topol meters per customer account from around $60 per month — a third model that fits B2B platforms particularly well.

Decision checklist

1. How many distinct templates will our customers create per month, in total? This single number decides the comparison.
2. What counts as a unique email in Stripo's contract? Get the definition in writing before comparing prices.
3. Do we need landing pages too? Only Unlayer covers them.
4. Is AMP or interactive email in scope? That points to Stripo.
5. Does our finance team prefer predictability to a lower floor? Flat tiers usually win that argument even at a higher number.

The number that matters

400 unique emails per month at Stripo's $100 tier. Below that, Stripo is dramatically cheaper than anything else in this category. Above it, the curve steepens toward $550 for 15,000 and the comparison with Unlayer's flat $250 platform tier becomes a real calculation rather than an obvious answer.
