Your customers expect emails to arrive immediately—not eventually. We constantly monitor service's delivery speeds and send your emails accordingly. We also offer Intelligent Mode which gives you the following benefits: 1) We monitor delivery speed of all the services and send your email with the fastest one. 2) We also do cost management to avoid long bills from your email providers by consuming free quota first. 3) You can tag an email as urgent for speed delivery or casual to cut cost. 4) You can also set the delivery duration which means in worst case if the email is not delivered in that duration, we will send it again with different provider.
