Email Booster

First you decide what source of emails you want boosted:

• Plain-text and HTML
• Campaign Monitor
• MailChimp
• Mad Mimi

Then Email Booster will:

• Analyze your email Subject and tell you how to improve it. It even checks against a massive database of words that can either help or hurt your conversions.
• Make sure your email Body is up-to-snuff with no bad code, enough content to not be flagged as Spam, and contains a mailing address (also less likely to be Spam)
• Check that your hyperlinks are valid.
• Scan your email with SpamAssassin (the best spam-prevention tool out there).
• Ensure your images are as optimized as possible and contain proper descriptors (in case they can't be loaded in an email client).
• And more...
