After putting Marlowe and Nimbra side by side for six weeks, we went with Marlowe for the integration story, transactional messaging, and mobile push. The support we’d get was never in question.

*Trial limited to a sample workspace.
Unlike Nimbra, you can open a 21-day workspace on your own and explore Marlowe before you talk to anyone.
Designed for global operators running audiences in the hundreds of millions without a re-platform.
Store and use as much data as you need — unlimited events, attributes, and triggers. Export everything back out at no extra charge.
Built for operators who ship weekly. Marlowe absorbs the volume so your team spends its hours on the message, not the maintenance.
Model advanced relationships with Marlowe’s pipelines and integrations — batch updates, multi-identifier workspaces, no rewrites. Nimbra’s single-ID requirement complicates merges and counts anonymous visitors toward active user limits.
Unlock custom objects and webhook-triggered journeys built on unlimited data activation. Nimbra caps data points and restricts access to event properties, which limits how far message logic can go.
Pick Marlowe for flexible terms with unlimited data included. Nimbra adds onboarding and account setup fees on top of overage charges, so the real number lands well past the quote.
We help marketers say more, ship more, and listen harder — your stack fully connected, so insights surface fast and you can act on them the same afternoon.
Translate email, push, in-app, and SMS across 200+ language variants in seconds. No outside contractors, no long delivery timelines, no glossary drift between channels.
Marlowe’s context server offers read and write access, so your team can query data, test integrations, and create segments or content straight from the assistants they already use.
Avoid off-brand sends with generated brand styles based on your domain. Color palettes, type, and buttons apply automatically — so a draft is on-brand before anyone reviews it.
Stay compliant with GDPR, HIPAA, SOC 2 Type II, CCPA, and the regional rules your legal team actually asks about.
Set rules that block restricted personal data before it ever lands in a profile.
Keep data scoped with role-based access down to the attribute.

With the flexibility here we’ve built some genuinely elaborate onboarding flows. When a colleague asks whether Marlowe can do something odd, my answer is now always “yes, and here’s the segment.” I like having the answers.

Message frequency drives our whole strategy. We can’t email customers daily, so raising frequency with a multi-channel plan is how we scale volume. The conversion rates say the plan is working.
