NeverBounce offers a free "Instant Bounce Analysis" with a recommendation on whether cleaning is required, before returning validation results and the option to download the new, cleaned list. The product claims an average processing time, variable to email type, of 2-10 minutes for 10k-strong lists, with a promise that the outputted clean list delivers 99.9% of validated emails. Validation results are displayed within color-coded pie charts, detailing percentages for valid, invalid, catchall, unknown and disposable numbers. Real time verification is also available for individual, one at a time email address entry with the inclusion of 1,000 free API-based verifications included each month. NeverBounce's custom developer API and webhook can be used from scratch or via a selection of drag and drop wrappers, boasting usage and submission attempt monitoring etc. The service can also be embedded into an online form more simply for non-developers thanks to a copy and paste JavaScript widget that also identifies origin and browser of every submission.
