Nearly everyone has experienced the frustration of sending an email, only to later learn that the recipient never received the message. We know how to navigate around the pitfalls that cause non-deliveries, and we work with you to employ message authentication methods (such as SPF and DKIM), to maximize the likelihood of your messages reaching their recipients' inboxes - and not their spam folders.
Know instantly when recipients' mail servers have accepted delivery of your messages, or if message delivery was unsuccessful or deferred. Check delivery status of message through your account at our site, or opt to receive delivery status notifications by email. Upon successful delivery, status notices include a delivery transcript with a receipt acknowledgement from the recipient's mail server - similar to a transmission report after sending a fax.
Receive alerts when your sent messages have been opened by their recipients. No more waiting for replies, wondering whether your messages never reached their recipients, or if your recipients are just blowing you off!
Like 'certified mail for email' - this feature requires recipients to confirm receipt of important attached documents (such as invoices, important letters, legal documents, etc), so that you can be sure that your recipients are in receipt of documents that you've sent them.
Incoming and outgoing connections to and from UltraSMTP are secured using the most secure SSL/TLS standards, to prevent eavesdropping and interception of messages and passwords.
Use UltraSMTP to send mail from any standard mail client, from any device, from any wired or wireless internet connection, and from any email address.
Configure your preferences for every feature of UltraSMTP through our control panel accessible through your account at our site.
UltraSMTP is not a free email service. Nor is UltraSMTP a bulk email service. Offering free or bulk email services invites abuse and quickly leads to mail server IP addresses getting blacklisted by spam filters. We do not offer free or bulk email services, so that the services that we do provide to our paying clients are of utmost reliability.
For larger organizations and enterprise clients, we offer fully-managed private dedicated servers running our custom UltraSMTP software.
