Validating disposable email addresses is crucial for several reasons:
Deliverability: DEAs can affect your email deliverability rates, as many disposable email services have a limited lifespan. Reputation: High bounce rates from sending emails to DEAs can harm your sender reputation. Engagement: DEAs are less likely to engage with your content, leading to lower open and click-through rates. Cost: Sending emails to DEAs can be wasteful, as most email marketing platforms charge based on the number of contacts or emails sent.
