An invalid email address is one that cannot receive emails due to various reasons: it may have syntax errors, the domain might not exist, the mailbox might be full or deactivated, or the mail server might be incorrectly configured. Invalid emails can also include addresses with typos or deliberately fake addresses.

Invalid emails can significantly impact your email campaigns in several ways: they increase bounce rates which can damage your sender reputation, waste your email sending quota, skew your campaign metrics, and potentially get your emails marked as spam by email providers. This can lead to decreased deliverability rates for your entire email campaign.

A DEA, or disposable email address is a temporary, throw-away address that expires after a short period of time. DEA provider websites offer a service where users can generate a temporary email address.

Disposable email addresses are temporary and provide no real user engagement. Users registering with temporary emails often aim to abuse free trials or services, consuming your business resources without any intention to become paying customers. These users waste server resources, support team time, and marketing efforts while providing no return on investment. Additionally, keeping these addresses in your mailing lists leads to unnecessary costs for storing and sending emails to non-existent recipients.

Disposable emails can harm your email lists and marketing campaigns. When users register with disposable email addresses, it can result in a high bounce rate, lower deliverability, and damage your sender reputation. Moreover, it may distort your analytics and make it harder to reach your target audience effectively.

A real-time email verification API is an excellent way of stopping disposable emails from getting into your database.

Yes, you can cancel or change your plan at any time. However, your plan will remain active until the end of the current billing cycle.

Here are some of the common names for disposable email addresses (DEAs): Throwaway email address, One-off email address, Single-use email address, Burner email address, Temporary email addresses, Use-and-throw email address, Fake email addresses, Trash email addresses
