A: Hello!

Thank you very much for your question! :)

The credits are LIFETIME, so they never expire. You can use now, 3 months from now or even later. No problem. After using your AppSumo coupons, you can purchase credits directly starting from only $4 for 1,000 credits. Kindly visit our pricing page (https://thechecker.co/pricing) for more information.

We have the Javascript Widget which allows you to verify emails in real-time by just copying and pasting one line of code.

Thank you.
