The SMTP OUTBOUND connector gives you the ability to send email directly from your applications, without ever touching or storing it in the cloud. It's the powerful combination of dedicated IP addresses and physical infrastructure that drastically reduces latency, increases throughput, and ensures reliability.

The key to a successful email delivery is the ability to send it to the right recipient. Sending an email to a wrong recipient, also known as the “bounceback effect” may create a wrong impression of your organization as some important emails such as those containing flight information, hotel bookings and flight tickets etc., may not reach their recipients resulting in huge financial loss. Bounce-Back Robot checks the validity of the recipients email addresses and takes an intelligent decision on whether to bounceback or deliver depending on how many times you have tried and failed already to send an email to that recipient.

There are several parameters that you can customize as per your requirements. Email marketing is gaining more popularity since it doesn't require any extra effort or cost of printing. However, setting up email campaigns with the help of SMTP server takes some work on your part. Once you buy SMTP server for email marketing, you need to set it up in a way suitable for your operations.

• The Anti-Spam SMTP Proxy allows you to specify your allowed and blocked lists of IP addresses, website domains, and email addresses so that the emails related to those lists can be allowed or denied entry to your email address, as the case may be.
• With adcrux bulk email sending software, you can send up to 25,000 emails in an hour. With our email delivery reporting software, you'll know instantly when your recipients have opened your emails. We offer both free and paid bulk email sending solutions.
• When the timeout period is reached, the SMTP server will recall the emails that hadn’t reached the recipient. This increases your chance of delivering your emails to the desired recipient’s inbox. Admins can also define a number of emails that can be sent in one session. Once this number is exceeded, further email sending will be paused for a certain time in order to decrease server load and avoid overload.
• Whether you need to send out an email newsletter, or an occasional notice about a new product, this function will send whatever you upload to your subscribers. You can use the checkboxes above to choose how often the SMTP server will check for new material, and how many times it will check for each set of subscribers. Example: 5 days between downloads, 3 times per each download.
• Set the size limit for the outgoing emails by your server.
• With the SMTP Server, you can set the IP address of the SMTP Server to use for outgoing emails. It is no longer necessary to enter the IP address manually in the outgoing email settings.
• TLS is a secure method for encrypting messages between mail servers. You can enable TLS in your email program to make sure messages are delivered securely, or disable it if you think your network may not be secure.
• It provides a centralized configurable SMTP gateway for receiving email from external senders through third-party gateways acting as a front-end to your organization's local network. The SMTP Inbound service also supports directory harvesting for bulk commercial email.


SMTP service providers are widely used these days by any company that needs to send bulk emails. SMTP servers are the backbone of the email marketing process. The provider chosen must guarantee high-quality deliverability, exceptionally high uptime, speed, reliability, and security. It is not enough to find a good SMTP host; you should also make sure that it's secure or encrypted for higher performance.
