Frequently Asked Questions

Find answers to common questions about email verification.

Why shouldn't I just use my ESP’s built-in cleaning?

Most Email Service Providers (ESPs) only "clean" an address after you try to send to it and it bounces. By then, the damage to your sender reputation is already done. VitaMail identifies invalid addresses before you hit send, protecting your deliverability score from the start.

Is an API really not necessary for cart recovery?

While an API provides real-time protection, many lean teams find it adds unnecessary technical debt. By using bulk cleaning on your newest signups weekly and implementing client-side typo prompts, you achieve roughly 95% of the same benefit without needing a developer to write a single line of integration code.

What is a "Catch-All" or "Risky" email?

A catch-all (or "Accept-All") server is configured to accept mail for any username, making it impossible to verify with 100% certainty without sending a real email. We label these as Risky. We recommend segmenting these users and sending to them separately or at a lower frequency to protect your main sender reputation.

How often should I clean my e-commerce list?

For high-volume stores, we recommend a weekly hygiene routine for new signups. For smaller stores or those with lower traffic, a monthly deep clean of your active segments is usually sufficient. Always run a bulk check before major sales events like Black Friday or Cyber Monday.

Will cleaning my list decrease my total subscriber count?

Yes, but it increases your active, reachable audience. Having 10,000 subscribers with a 10% bounce rate is significantly worse for your business than having 9,000 subscribers with a 0.5% bounce rate. Quality always beats quantity when it comes to inbox placement.

Does VitaMail store my customer data?

We prioritize security. Your uploaded lists are processed for validation purposes only and are automatically deleted from our servers after a set period. We provide the results you need to update your ESP, then we clear the deck.
