Inspect email linksFree email research tools
Get an answer, then get back to work.
Two focused tools for the evidence marketers inspect most: where an email sends readers, and when a sequence arrives. Each runs in your browser and gives you a usable result without signing up.
Email Sequence Cadence Calculator
Enter the subscription time and captured messages. See first-response time, send gaps, median cadence, and the full sequence in order.
Calculate cadenceWhat these tools can and cannot tell you
The link inspector reads the HTML you provide. It does not visit links or claim that a redirect resolves to a destination it cannot see. The cadence calculator uses the timestamps you enter and your device's local timezone. Neither tool measures inbox placement, engagement, or conversions.
