Most organizations calculate email delivery rate by subtracting *all* delivery failures from the total emails sent. Delivery rates typically range from 80% to 98% when following best practices.
For instance, in 2009 Business to Consumer mailings, the median delivery rate was 80.4% according the research firm Marketing Sherpa. However, the median delivery for Business to Business mailings in 2009 was 92%. We strive for delivery rates over 95%.
BombBomb ensures high delivery rates by implementing the latest email standards including sender ID, by building and maintaining an outstanding sender reputation, and through our whitelisting program for building strong relationships with Internet Service Providers.
