Why you should verify your email list before sending bulk email
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 reached your customers and shows inbox providers that you’re not following best practices. This bounce, in turn, hurts your sender’s reputation and you’ll start to see negative impact on your overall email deliverability as a result.
You spend thousands of dollars and hours of work 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 validation 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.
How often should you check your email list?
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, switch domain names, leave their inbox service provider, and more. In other words, about 25% of your email database goes 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. We’re an industry-leading email service provider (ESP) that has partnered with leading companies like Lyft, Shopify, and Etsy to help improve their email performance. See what we can do for your small business!
