Reporting - Sugar Suite reporting turns data into actionable information. Managers can monitor business performance across customer segments, marketing campaigns, sales opportunities and customer satisfaction levels. Charts can be customized to meet the individual roles of users or to track key metrics across the organization. Underlying the reports is that actual data, so managers can drill down and explore the opportunities shaping the entire business.

• Posting to the mailinglist is via a webpage. It is therefore a one-way announcements system, directed from you to your audience.
• phplist enforces a double opt-in subscription system. Subscribers who enter their details in a web based subscription page, will receive an email and have to action their subscription to receive emails.
• It is designed to be able to deal with a very large amount of email addresses. If a sending fails halfway, the next process for sending simply continues where it left off, without duplicating emails to users.
• Users can sign up to multiple lists. If a message is sent to multiple lists, they will only receive one copy of the email and not as many as the number of lists they are subscribed to.
• Open Tracking. You can see how many users opened your email. This is a rough indication, as many mail readers do not allow this, but it can still be quite useful.
• Click Tracking. You can enable tracking all clicks of all URLs in the emails you send and PHPlist will report on the clicks on every single email. This can be viewed by message, URL or user
• Send a Webpage. Just tell PHPlist the URL of a webpage you want to send to your users and it will fetch it and send it out. You can even give the URL some user specific parameters that will fetch a different URL per user.
• Templates. It is very easy to adapt the public pages of the system to fit into your website. You can upload a header and a footer of all pages to make the pages fit your requirements.
• Attributes. You can specify information you want to get from users when they sign up. When sending a message, you can use this information to select the users that need to receive the message. For example you can add geographical information. When people sign up, they can identify the geographical location they're in and when sending an email you can determine which locations need to receive the message.
• Multiple subscribe pages. You can design your own subscribe pages and you can have different pages allowing users to sign up to a selection of your lists and only enter a selection of your pre-defined attributes.
• Personalisation. You can use the attributes you define in the emails you send, to make every email personal to the user who receives them.
• PHPlist supports HTML emails. If a user indicates they want HTML email they can receive it that way. If unknown the system has a bias to send text emails to users.
• There is a choice of which HTML editor you want to use in order to create your emails. These editors are pulled in from other open source projects that specialise in clever HTML editors.
• Multiple List managers. One Super user can assign lists to multiple list managers, who can control their own pool of users and lists. The Super user can "prepare" messages that can be chosen by list managers to send to any of the lists they control.
• Easy import and export. Use TAB delimited files to import your existing list of users or to export the users on the PHPlist system for use in your in-house database.
• Personal Details. Every email a user receives will contain a personalised URL to update the users' preferences. This way your users can update their own information and your database is always up-to-date. Unlike most other mailinglist managers users can change their email address when updating their personal details. This is a major benefit to both you and your users as many people often change their email address, and this feature makes sure that they don't disappear from your view.
• Attachments. You can add attachments to your message. They will be included in the HTML emails. The users who receive text will get a special URL mentioned in their email telling them where to download the attachment from your website.
• Batch Processing. To facilitate shared hosting environments, you can specify the maximum number of emails to send in a time period you identify. This can also be overridden by ISPs who can set these values server wide to apply to any PHPlist installation on that machine.
• Set up Throttling to make sure that the load on your server does not become excessive so it halts
• You can also use Domain Throttling to make sure that you don't send too many emails to one domain within a certain time frame and get very unfriendly with the system administrators of the receiving domain
• ISP Friendly. Apart from the limit on values for batch processing that the ISP can enforce, there is an additional option for ISPs to suspend sending during busy times in the day.
• Embargoed sending. You can create a message and tell the system to only start sending it at a certain date and time in the future.
• Repetition. A message can be repeated automatically. Currently this is only useful when the message has "filesystem attachments", because they are refreshed at time of sending.
• User management. You can use several in built tools to handle large databases of users. Users can be reminded to confirm their subscription and invalid emails will be found automatically, or fixed whenever needed.
• Bounce handling. Bounces can be processed and users will be automatically unsubscribed when too many emails to them bounced. This can be corrected by the administrator in case the unsubscription was incorrect.
• Advanced Bounce handling. You can specify regular expressions that match a bounce and identify actions on each of these. This means that you can teach your PHPlist installation to distinguish between hard and soft bounces.
• Manual Text entry. By default PHPlist will turn your content entered as HTML into plain text for the users who want to receive text, but it is also possible to do this manually if you wish to do so.
• Automated PDF creation. To ensure users can read the message regardless of mail reader, the message can be automatically converted to PDF and attached to the email.
• RSS feeds. PHPlist can be set up to read a range of RSS sources and send the contents on a regular basis to users. The user can identify how often they want to receive the feeds.
• PHPlist is now also available in languages other than english, although the translation work is still in progress
• Easy install. Just copy the files to your website folder, tell the login details of the SQL database and it's done.

The Webalizer is a fast, free web server log file analysis program. It produces highly detailed, easily configurable usage reports in HTML format, for viewing with a standard web browser.

It was written to solve several problems that I had with currently available analysis packages. A vast majority of them were written in Perl or some other scripting language, and took forever to run. Some were not free. Some even produced wrong results, or results that were not in a format I found very useful.

In order to get the stats I wanted, in a format that I liked, I wrote The Webalizer and have made it available here, to anyone who wants it, for any purpose. Starting as a simple Perl script with limited capabilities, it has grown into a full featured, robust and fast analysis tool, being used by thousands of systems around the globe.
