Our pricing model is very clear and depends on the accuracy level you need for your validations; the higher the level, the higher the processing and mainteinance costs for us, thus the higher the final price.

Price (per item) $0.001 $0.01 $0.03


There are no setup costs, nor there are monthly or annual fees.

We already offer very cost effective and competitive pricing. Our volume discounts rewards you even more by using the total volume you purchased over the last 30 days to determine how much your next email validation will cost.
