Bad email addresses = bad news.
That’s because bad email addresses usually result in a hard bounce.
That email you’ve spent hours crafting and optimizing? It never reaches your customer...and shows inbox providers that you’re not following best practices, hurting your sender reputation. And you’ll start to see negative impacts on your overall email deliverability as a result.
You spend thousands of dollars and hours acquiring email addresses. But a bad email address? That’s not just a lost customer — it’s all that time and energy wasted. Don't let typos clog up your email list with invalid email addresses. Use email checking tools to ensure you're capturing every customer along the way.
Mailgun's email verification tool can lower your bounce rate for your email campaigns by up to 20%. Supercharge your email marketing campaigns with Mailgun's powerful email verification tool.
Well, pretty often.
That’s because when you collect a person’s email address, you’re only collecting one snapshot in time. They may change email addresses, domains, leave their email provider...causing 25% of your email database to go bad every year. We recommend running a full email verification on your email list annually.
If you need help with your overall email deliverability strategy – Mailgun can help. Our email experts have partnered with leading companies like Lyft, Shopify, and Dell to help improve their email performance with an industry-leading email service.
