Embed our calculators, free
Both of our calculators run on any site with one line of code. No signup, no API key, no license to accept, and nothing tracked about your visitors. Keep the attribution link and they are yours to use.
What you can embed
SMS segment calculator
Counts GSM-7 and UCS-2 segments properly, including the nine extension-table characters that cost two each and the surrogate pairs that make one emoji cut capacity from 160 to 70. Most calculators get at least one of those wrong.
<div data-bluereacher="segment-calculator"></div>
<script src="https://bluereacher.com/embed.js" async></script>iMessage ROI calculator
Takes a list size, a reply rate and a deal value, and works out what a channel change is actually worth. Visitors put in their own numbers rather than reading ours.
<div data-bluereacher="roi-calculator"></div>
<script src="https://bluereacher.com/embed.js" async></script>How the embed works
The loader script finds every element on your page with a data-bluereacher attribute and drops an iframe into it. Include the script once no matter how many widgets you place. It is roughly 1 KB, loads asynchronously, and blocks nothing.
- Styles are isolated in both directions, so nothing on your page can break the widget and the widget cannot break your page.
- The frame measures itself and posts its height to the loader, so it sizes to its content instead of scrolling inside a fixed box.
- Widgets load lazily, so one below the fold costs nothing until somebody scrolls to it.
- If you render widgets after page load, call
window.BlueReacherEmbed.mount()to pick up the new containers.
Questions
Are the embeddable calculators free?
Yes, free with no signup and no license to accept. The only condition is that the 'Powered by Blue Reacher' link stays visible, which it does by default. Use them on client sites, agency sites, internal wikis, or anywhere else.
Do the widgets track my visitors?
No. The widgets run entirely in the browser, set no cookies, and send nothing about your visitors anywhere. The segment math happens locally as somebody types, and no message text ever leaves their machine.
Will the widget break my page styles?
No. Each widget renders inside an iframe, so its CSS cannot touch your page and your CSS cannot touch it. The frame reports its own height back to the loader, so it resizes to fit instead of scrolling inside a fixed box.
Can I embed more than one widget on a page?
Yes. Add one container div per widget with the matching data-bluereacher value, and include the script once. The loader finds every container on the page and mounts each one.
Why does Blue Reacher give these away?
Because a calculator that lives on your site is a better introduction than an ad. Somebody working out their SMS segment costs is the exact person for whom a channel with no per-message fees is interesting, and the link at the bottom is how they find us. Fair trade both ways.
Working out what SMS costs you per segment?
On iMessage there are no segments, no per-message fees, and no A2P registration. A line is $249 a month with unlimited messages. Lines pace at 50 opted-in / 30 cold new contacts a day to stay deliverable; replies are never metered.
