Case Study zum Thema E-Mail Zustellbarkeit

Yahoo! Mail, Gmail, AOL and similar providers track senders’ reputations by IP address. This is partly why sending emails from dedicated IPs (instead of IPs you share with others) is the most effective tactic for improving deliverability, according to the MarketingSherpa 2011 Email Marketing Benchmark Report.

Many smaller companies, though, cannot manage a dedicated IP well enough to build a strong reputation and are better off using shared IPs, says James Thompson, Email Systems Manager, Infusionsoft.

“What we found is that most small businesses really don’t have the resources to be able to dedicate the kind of attention and maintenance required to maintain a good status on a dedicated IP,” he says.

Thompson oversees the sending of about 40 million emails each week for clients at Infusionsoft, a marketing automation software provider that caters to small businesses. He is tasked with maintaining the email architecture and deliverability for clients across the system.
