Principles of an Effective Cybersecurity Strategy

According to MetricStream’s, ‘The State of Cyber Security in the Financial Services Industry’ report, around 66 percent of financial services institutions have faced at least one cyber-attack in the last 12 months. The cost of this can even result in a complete shutdown of the business."

Third Party ESP as a solution to the problem:

After a series of customer support discussions with the cloud service provider, we decided to go for a third party ESP for the requirement. Incidentally we found that a lot of Amazon EC2 and RackSpace Cloud Hosting customers are using third party email service for their cloud hosting. Are there any added advantages in going for third party email service providers? Yes. Is there any disadvantage in going in for them? Yes, there is. The addition of value comes by way of even better email management system and control; and in some cases API s for more customization. The developer API can be used for calling web service to send mails. More email related statistics can be obtained. Programmatically we can track the email delivery status by the transaction id generated by email sent through API. The following is one of the screen shot of statistics obtained from service.

The statistics provided include average number of emails sent per day, total jobs, recipients, delivered emails, bounced emails etc., The graph shows the bouncing percentage.

The disadvantage of third party ESP is definitely additional cost involved. And also, sharing data with another provider system should be a definite concern for some.

Implementation Details

Implementing third party email service provider is guided by the ESPs itself. It may involve updating DNS Records. This is done by creating SPF records. DKIM is another concept. SPF stands for Sender Policy Framework and DKIM Domain Keys Identified Mail. SPF is the basic email validation system. In the public DNS record, we can specify SPF record where in we create authorized servers to send emails. DKIM is identified mail with enhanced with enhanced protocol.

Pricing Plans of Third Party ESPs:

The pricing plans of third party ESPs vary. Depending on our requirement, we can choose the right one. Some ESPs are suitable for transactional emails. Some ESPs are suitable for bulk mailing. For transactional mail needs, pricing goes as $ 1 or 1.5 per thousand mails. 10 mails per cent. Usually there is a free first 1000 emails to test the service. Bulk mailing pricing can go on monthly payments with a monthly fee and charge for mails sent in thousands or millions.


Worldwide cloud adoption is increasing for various compelling reasons. More and more websites/ web applications are being hosted in cloud. As the adoption increases, there are different technicalities and methods being tried and established; out of this best practices are also emerging. We saw an example scenario of email sending from cloud servers through third party email service providers in this article. We request that the readers experience in this regard can be shared here as comments.
