We are using Amazon SES ( https://aws.amazon.com/ses/ )for sending transactional and marketing emails.
Amazon SES offers notification for email transactions over Amazon SNS ( https://docs.aws.amazon.com/ses/latest/DeveloperGuide/notifications-via-sns.html ).
I use TextWrangler on my Mac as a text editor. TextWrangler has a feature called “Text Filter” you can run some custom filters on text file.
We have landing pages with heavy traffic like over 1 million page-view daily. Regularly, new pages are added, some of them are updated and some of them are removed from production.
