Test if your emails will be spammed, using real accounts.

#3 Product of the DayFebruary 15, 2020
Vetter allows you to safely determine whether an email you wish to send will be marked as spam. This is done by testing the email against a network of real email accounts, and checking whether it ended up in inboxes or was spammed.

Nice idea, will def give if a try this week
I think his could perfectly work as a Chrome/Firefox extension where marketers test campaigns from Mailchimp, Mailgun, Mailjet... before spreading them, it's better than copying manually the object and the content.
@medyo80 You're quite right. Chrome and Firefox extensions are part of our product roadmap.
Nice idea! Whether an email is put into Spam folder is personalized, i.e. depends on user email behavior. Do you have a number on how accurate your prediction is?
@nguyenkims Boy, that's a tough one! We're still gathering data on this, and will probably write a blog post when done. What I can say for now is that the predictions do seem to be fairly accurate, especially if you plug in your own email account/service (as the email sender). For sure, we've used Vetter's predictions to fine-tune our own email messaging. We've improved deliverability for Hotmail/Outlook/Live from ~10% to 20% to ~90% to 100% with this. Of course, this is anecdotal and YMMV!
Cool idea, good luck!
Amazing idea, please sign me up for the Beta :)
