FOR EMAIL MARKETERS

Volume, tests, segments. And a bill that doesn't move.

Five subject variants with the winner chosen automatically. Segments built on who last opened and who last clicked. Geo maps, per-recipient logs and a report you can share without a login. And a price set by the software, not by the size of your list.

THE TAX ON GROWING

You were being charged for doing your job well.

Per-contact pricing has an odd incentive built into it. Every subscriber you win raises the invoice. Every list you clean lowers it. So you sit there deciding whether to prune, or to keep paying rent on addresses that have not opened anything since March.

CleverlyBox prices the software. Business is $50 a month for 100,000 contacts — and sending is included, so there is no AWS console and no second invoice from a mail relay. The verification tool, the automation builder and the AI copy are in the same login.

A/B TESTING

Five subject lines. One winner. No spreadsheet.

Run up to five subject variants on a campaign. Pick the criterion — open rate or click rate — and the winner is selected and sent to the remainder of the list. You do not export a CSV, do the arithmetic, and schedule a second send by hand.

Campaigns come in regular, plain-text and A/B. Plain-text is not a formatting quirk; it is a deliverability decision, and it is a click of the mouse rather than a rebuild.

SEGMENTATION

Engagement is an operator, not a vibe.

"Engaged" only means something if you can express it. Segments here take engagement operators directly: last opened within N days, last clicked within N days. Stack those with tags, custom-field matching, created-date and verification status.

01 / RECENCY

Last opened / last clicked within N days

The two operators that do most of the work. A 30-day opener and a 30-day clicker are different people with different intent, and once you can name them separately you can write to them separately.

02 / TAGS

Tag membership, in or out

Tags get added by forms, by flows, by the API, by hand. Segment on holding a tag or not holding it, and your automations can add and remove them mid-flow.

03 / FIELDS

Field matching on your own data

Plan, region, seat count, last purchase, whatever you push in. Custom fields are matchable, and an attribute-changed trigger can start a flow the moment one of them moves.

04 / HYGIENE

Verification status and created date

Send the big one to verified addresses only. Treat a fortnight-old subscriber differently from a three-year one. Both are segment conditions, not exports.

ANALYTICS

Down to the recipient. Out to a public link.

Opens and clicks are the start. Geo maps show where the campaign landed. Per-recipient logs tell you what one named person did with it. CSV export takes the lot into your own analysis. And any report can be published to a URL that opens with no login at all.

Opens & clicks
Per campaign, per link
The headline numbers, and which link inside the email actually did the work.
Geo maps
Where it landed
Opens plotted geographically — useful when send time and region are the same conversation.
Per-recipient logs
One row per person
Delivered, opened, clicked, bounced — by contact. The answer to "did she get it?"
CSV export
Take it with you
Export the report and do your own maths. Your data leaves whenever you want it to.
Public report URL
No login required
Send the link to a client or a director. They see the numbers without an account or a seat.
Webhooks
Opens and clicks, live
Push the events into your own warehouse or CRM as they happen, via webhook.

SENDING AT VOLUME

Sending is included. Or bring your own.

On day one, sending works. There is no relay to provision and no console to learn. From the Business tier you can also route through your own provider — Amazon SES, SendGrid, Mailgun, SparkPost, Elastic Email, Blastengine, Gmail OAuth, Sendmail or any SMTP server. Nine in total.

Deliverability is handled where it should be: SPF, DKIM and DMARC verified in-app, an IP warm-up engine with linear and exponential ramps, automatic pause when bounce or complaint rates spike, one-click unsubscribe to RFC 8058, a blacklist, and a banned-word check before the send leaves.

QUESTIONS

Straight answers.

How many subject lines can I test, and how is the winner chosen?

Up to five variants per campaign. You choose the criterion — open rate or click rate — and the winning subject is sent to the remainder of the list automatically. No manual export, no second campaign built by hand.

Am I charged more as my list grows?

You are charged for the plan, not per contact. Free covers 1,000 contacts, Starter 5,000 at $20 a month, Business 100,000 at $50. Sending is included in all of them, so growth does not quietly turn into a bigger invoice.

Can I segment on how recently someone engaged?

Yes — last opened within N days and last clicked within N days are first-class segment operators, and you can combine them with tag membership, custom-field matching, created date and verification status.

Can I get the raw data out?

Per-recipient logs are exportable to CSV, and open and click events can be pushed to your own systems by webhook. There is a REST API on top. Your data is not held hostage by the reporting screen.

Do I have to use your sending infrastructure?

No, but you can. Sending is included with no setup. From the Business tier you may instead route through Amazon SES, SendGrid, Mailgun, SparkPost, Elastic Email, Blastengine, Gmail OAuth, Sendmail or any SMTP server.

Test properly. Segment properly. Stop paying per name.
