Now for the finale, the last panel in the Email Insider Summit. Panelists are charged with summarizing what they learned and suggesting what they can put in place Monday morning based on their takeaways.

As big brands consider performance marketing, Adconion Direct's Amanda Currie says hurdles in convincing them include the CAN-SPAM Act and compression files, but she says there is a benefit there.

Beyond.com's Geri Weltz says at the Email Insider Summit that if a company can't capitalize on moving emails in "real-time," think about "relevant time."

At the Email Insider Summit, Beyond.com's Geri Weltz says the company has an in-house content management system. She advises email marketers to take advantage of transactional mail data and give people something else interesting to bring them back to the site, based on what you know consumers are interested in.

Real-time in-box activity has such potential on paper. An Email Insider Summit panel will now try to answer why adoption may not be moving as fast as one would think.

With his keynote at the MediaPost Email Insider Summit, PaperStyle.com's David Grocer says his company has benefited from Google Analytics to collect data as a small company.

David Grocer, a PaperStyle.com executive, is kicking off the third day of the Email Insider Summit with a keynote addressing behavioral targeting.

Personalization with email has been a key theme throughout the Email Insider Summit. How to improve it? Carnival Cruise Lines' Roger Foisy said when he joined the company it had three creative agencies. Email marketing has been brought in-house. He said the company looks to "identify simple variables" to insert into emails to improve personalization such as whether a person has cruised before or is a loyal customer.

"Creepy factor" aside, marketers run into problems with ad (and email) personalization when they fail to factor in consumers' changing tastes. Roger Foisy, Senior Manager of Email Marketing at Carnival Cruise Lines, used the analogy of old relationships to illustrate the point. After taking a trip to Mexico, travel marketers wouldn't leave him alone about the vacation destination for three years, he told attendees of MediaPost's Email Marketing Summit on Friday. "They married me to Mexico!" Foisy recalled. Trouble is, he said, "I had moved on!"

Personalization is important to a good experience, but marketers need to walk the fine line between getting personal and being creepy. In a the final panel at the Email Insider Summit today called, "Creating Breakout Email Content," Erin Junge, manager of Web design & development at Mutual of Omaha, summed it up by saying, "I like it when a brand gets me but I don't want them to get me too much."
