Frequently Asked Questions

Everything you need to know about email verification, deliverability, and protecting your sender reputation.

Email verification is the process of checking whether an email address is valid, active, and capable of receiving messages without actually sending an email to that address.

A bounce rate is the percentage of emails in a campaign that could not be delivered to the recipient's inbox. High bounce rates can damage your sender reputation and lead to blacklisting.

Sender reputation is a score assigned by Internet Service Providers (ISPs) to an organization that sends email. A higher score means ISPs are more likely to deliver emails to the recipients' inboxes.

Disposable email addresses are temporary, short-lived accounts often used to bypass sign-up requirements. They are typically deleted shortly after use, making them low-value for marketing.

Role-based addresses (e.g., admin@, support@, sales@) are associated with a function rather than a specific person. They often have multiple recipients and higher complaint rates.

An accept-all (or catch-all) domain is configured to receive all emails sent to it, even if the specific mailbox doesn't exist. Verifying these requires advanced predictive analysis.

We recommend cleaning your email list at least once every 3 to 6 months, or immediately before any major campaign, to account for 'email decay' as people change jobs or providers.

While no service can guarantee 100% delivery due to external factors like content filters and recipient server downtime, VerifiSaaS removes up to 99% of invalid addresses.

A spam trap is a valid email address used by ISPs and blacklist providers to identify and block senders who don't follow email best practices. Sending to one can severely damage your reputation.

Improving inbox placement requires a combination of list hygiene (using VerifiSaaS), high-quality content, proper authentication (SPF/DKIM), and consistent sending patterns.
