Which one is actually better?

It depends on your roster. If your clients are spread across several email platforms, Hiro covers more ground and SendLens will not work for the non-Klaviyo accounts at all. If your roster is Klaviyo and you want predictive analytics, prospect audits and the ability to push segments back into Klaviyo, that is where SendLens goes further.

Some agencies do, using one for multi-ESP roll-ups and the other for depth on their Klaviyo accounts. Both read from Klaviyo without changing anything unless you explicitly ask them to, so running them side by side during a trial is safe.

What does switching involve?

There is no data to migrate. SendLens reads from Klaviyo directly, so you paste each client's Klaviyo API key and the backfill starts on its own. Last week's performance is ready by the next day.

Do I need to book a demo to try SendLens?

No. Start a 7-day trial from the site and connect Klaviyo yourself. No card is charged until the trial ends.

The detailed breakdown

A dash means the capability is not documented in Hiro's public help centre or marketing site as of August 2026. It is not a claim that the product cannot do it.

Customer and predictive analytics

The clearest split between the two products. Hiro is descriptive reporting done carefully; the predictive layer is where SendLens goes further.

The biggest gap

Reporting tells you what happened. This tells you what happens next.

Hiro's documented analytics are descriptive: cohorts, LTV, attribution, all measured carefully after the fact. SendLens adds the predictive layer on top of that, on every plan including the entry tier.

Eleven RFM segments, with thresholds you can tune per brand
Churn risk scored per customer, with the revenue at risk attached
Predicted next order date, so win-backs land while people are reachable
30, 60 and 90-day revenue forecasts with confidence intervals

SendLens customer analytics showing RFM segments and churn risk

Acting on it

Both have AI. Only one can build the segment.

Hiro's documented AI writes report notes and retrieves data for Claude. Ask SendLens does that too, and can then draft the segment, list or campaign in Klaviyo for you to approve. Nothing ships without a human clicking confirm, and deleting anything makes you type DELETE.

Ask questions in-app, no external AI account to connect
RFM tiers written back to Klaviyo nightly, so segments stay live
Every write is approval-gated and logged
A hard daily usage cap, so the AI cannot run up a bill

SendLens AI insights with prioritised actions

New business

Neither tool wins you the client. One of them helps you pitch.

Hiro reports on the clients you already have. SendLens also runs a full lifecycle audit on a prospect's Klaviyo account before they sign, so the pitch deck is proof you already understand their account.

Run an audit on a time-boxed prospect account, no setup from them
Lifecycle gaps named across eight stages, with value estimates
Campaign creative screenshotted and critiqued
White-labelled in your agency's colours

How we compiled this

Methodology and sources

Every Hiro capability above was taken from their public help centre at docs.hiroanalytics.com, their marketing site, or their Klaviyo App Marketplace listing, reviewed in August 2026.
Where a capability is not documented we mark it “not documented” rather than claiming it is absent. Undocumented is not the same as impossible, and their product may well have moved since.
We have deliberately excluded figures that appear on unedited template sections of their marketing site, because they are not claims Hiro is actually making.
Pricing on their side is not published as a rate card; the figures shown come from their homepage FAQ and a worked example in their help centre.
Spotted something out of date or wrong? Tell us at hello@sendlens.io and we will correct it.

Common questions

We built SendLens, so treat it as a vendor comparison and verify anything that matters to your decision. What we can commit to: every Hiro claim here is sourced from their own public materials, we say plainly where Hiro is the better choice, and we mark anything undocumented rather than assuming the worst. If we have something wrong, email us and we will fix it.
