Frequently Asked Questions
How accurate are your calculators?
Our calculators use industry benchmarks sourced from Mailchimp, Campaign Monitor, HubSpot, and DMA research. Results are estimates — your actual performance depends on your industry, audience quality, and execution. We update pricing data quarterly and benchmark rates annually to ensure accuracy.
Can I embed your calculators on my site?
Yes! We offer free embeddable versions of all our calculators. Visit any calculator page and look for the embed option at the bottom. You can customize the color scheme to match your brand. Attribution link required.
Do you offer consulting or ESP recommendations?
We don't offer paid consulting, but our comparison pages provide detailed, unbiased ESP recommendations based on real pricing data and feature analysis. Use our ROI calculator to model the financial impact before making a switch.
How do you make money?
Open-rate.com is funded through display advertising and affiliate partnerships with ESP providers. We do not sell placement in our comparison rankings. Our editorial recommendations are independent and based on verified pricing data.
