Content

The HTML lang attribute does not have much impact on SEO when it comes to Google. Google has explicitly said they ignore the tag in favor of hreflang tags for multilingual sites.

Not quite.

While Google doesn't look at language tags, Bing does.

In fact, Bing doesn't use the hreflang tag when matching user language to page content. It uses what's called the "content-language" meta tag in the head of a document.

Average email marketing campaign stats of Mailchimp customers by industry

There are a lot of numbers in Mailchimp's reports on email and marketing automation, but you might be wondering how your stats compare to others in the same industry. What kind of open rates should companies like yours expect? How many bounces are too many? What data do content marketers rely upon to improve engagement rates? The more context, the better.

Mailchimp sends billions of emails a month for millions of users. Needless to say, we track a lot of data. So we scanned billions of emails delivered by our system (where campaign tracking was activated, and where users reported their industry) and calculated the average unique open rates, click rates, soft bounces, and hard bounces by industry.

We only tracked campaigns that went to at least 1,000 subscribers, but these stats aren't pulled from a survey of giant corporations with million-dollar marketing budgets and dedicated email marketing teams. Our customers range from 1-person startups, small businesses to Fortune 500 companies, so the whole spectrum is represented in this data. Here's your apples-to-apples comparison with others in your industry.

The data provided on this page was last updated in October 2019 and may vary from benchmarking data provided within the Mailchimp application.
