An unsanitized list is susceptible to the entry of spamtraps, disposable emails, no engagement, scraped emails and all types of emails that lead to the blocking of IPs and domains. Just 3% of delivery failures is enough to block a campaign and as a result, marketing or sales can't achieve their objectives, as communication is interrupted due to an unverified list.

Email validation allows us to generate real leads. With this, sales professionals are able to communicate with qualified audiences via email, developing strategies and actions that are, in fact, likely to achieve the expected results.

Today's valid email could turn into a bounce tomorrow. Obsolescence, lack of engagement, server problems, disposable addresses, among other reasons, can transform a valid contact into a risk for an entire base. Therefore, it is essential that checking emails is done frequently on the same list.

With valid emails, teams can develop strategies aimed at a segmented audience with high adherence capacity. Furthermore, professionals can generate relationship actions within the marketing funnel.

Low deliverability indicates that emails are being rejected by anti-spam filters. So yes, this negative KPI means that the sender's IP or domain could be a spammer.

With valid emails, it is possible to monitor campaign performance such as open rates, conversion rates, unsubscribe rates, among countless other metrics that can be viewed in performance reports.

The API allows you to build a healthy, bounce-free email list. This way, a campaign developed from a base of real leads has a much greater chance of success.
