Gammadyne Mailer is essential software for automating a business's email marketing. It can send personalized email campaigns as well as process virtually any type of incoming email, including sign-ups, opt-outs, and bounce-backs. The mailing list can be in a database, CSV file, or plain text file, and there are a full set of list management tools. Gammadyne Mailer's advanced SMTP engine supports multi-tasking, load balancing, HTML, mail merge, recipient filtering, throttling, and much more. Other capabilities include tracking, auto-responding, forwarding, list-serving, and follow-ups. But perhaps its best quality is its rock-solid design; it can run indefinitely without crashing or draining system resources. For over 13 years, Gammadyne Mailer has been grinding through the toughest of email tasks. No email marketing effort should be without it.
