UltraSMTP is a hosted outgoing SMTP email relaying service - used for sending email from standard desktop and mobile email clients, such as Mozilla Thunderbird, Microsoft Outlook, Apple Mail, etc., or for use by programmers and application developers to send auto-generated messages. UltraSMTP maximizes the likelihood of your messages landing in their recipients' inboxes - and not their junk folders, by applying message authentication methods and a host of other email best practices, to enable recipients' spam filters to recognize your messages as legitimate messages - and not spam. It also comes loaded with tools to enable you to track delivery of messages that you've sent, alert you when your messages have been opened by their recipients, and more.

With UltraSMTP, you get:

Greater Reliability

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.

Delivery Status of Sent Messages

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.

More

Opened Message Alerts

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!

More

Document Delivery Confirmation

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.

More

Security

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.

More

Mobility

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.

More

Manageability

Configure your preferences for every feature of UltraSMTP through our control panel accessible through your account at our site.

What UltraSMTP is NOT

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.
