How about a one-time subscription?
Easy! After your purchase, select "Off" from the Auto-Renew Plan's dropdown list on the subscription page.
How does a subscription work?
A monthly subscription of 5,000 lookups is good for either 5,000 lookups or for one month, whichever comes first. A subscription runs for either the number of lookups or for the period of time specified.
Does Melissa have a refund policy?
Yes, Melissa does have a refund policy. Please visit ourMelissa Refund Policypage to read about how our refunds work and to fill out our Refund Request form.
What is address validation vs. verification?
Validation is the process of confirming that a specific address exists. Verification goes an extra step: it compares an address against trusted reference data to confirm that mail can be delivered to the address. The verification process can also make corrections to the address and standardize the format. Melissa Data’s solutions provide both address validation and verification.
What happens when a subscription runs out?
It renews at the same level as your current plan unless you have specified another plan or have turned the renewal off. Need to change plans? Change it on the subscription page.
