What really sets Zinidoo apart from the competition is its integrated email sending engine. Zinidoo can effortlessly handle tens of thousands of emails sequentially without ever having any problems that are common when sending to large lists, including:

• Exceeding the servers memory limit, which causes PHP to crash
• Trying to send emails too fast, which overwhelms the server and cripples any bandwidth-related activitiy, including the ability to view your website
• Sending too much data to the mail server, which can have your hosting account banned
• Duplicate sending to the same people over and over again because of a fault in the sending routine

Email marketing is a critical business tool, and when it goes wrong your business looks bad. You lose sales and you lose trust with your subscribers. By choosing Zinidoo you're making the smart decision to have your email campaigns sent using a proven email marketing system.

Some Technical Stuff

In Zinidoo, we've written a complete enterprise-level email sending engine. The email engine is 2,000+ lines of code. Compare that to the typical one line of code that most email marketing packages use to send out an email and you'll start to understand the complexity of Zinidoo.

I guess that leads to the question "what's so good about Zinidoo's email sending engine?". Here are the absolutely critical reasons why your business can't afford *not* to use Zinidoo's enterprise-level email sending engine:

• Zinidoo handles text, HTML and multipart email sending easily, without using any additional system resources.
• Popular email clients such as Hotmail and Gmail will strip certain characters from stylesheets in your emails, which can cause them to display incorrectly. Zinidoo makes sure this never happens to your campaigns.
• Zinidoo allows you to specify the encoding of your email campaign (such as ISO-8859-1 or UTF8) and that encoding is carried over with the email.
• All emails are sent efficiently using the least amount of system/mail server resources possible. The email engine handles image loading and only loads attachments into the email once, instead of one per-subscriber, for example.
• The email engine can effortlessly send using a third party SMTP server or our mail server, depending on your preference.
• The email engine automatically handles SMTP authentication and handles errors appropriately.
• The Zinidoo email sending engine can handle highly complex sends, such as when email campaigns or sequential autoresponders are sending out at the same time.
• Every single point of possible failure is handled by the email sending class, which means if something goes wrong the appropriate action will be taken to either inform you or work around the problem during a send.

We've made sure Zinidoo's email sending engine is rock solid and you can rest assured that no matter how many email campaigns you send, no matter how many auto responders you schedule and no matter how many subscribers you have, Zinidoo can do the job. Every single time.

Rock-Solid Stability and Robustness

To prove just how stable and robust Zinidoo is, we ran multiple sending tests before its release. Each test was performed three times, and we took the average results from each test.

• An HTML-only email
• Images were embedded
• Tracking links was enabled
• Tracking opens was enabled

We tracked the sending speed of 1,000 - 100,000 emails and here are the results of our tests are shown below. As mentioned earlier, each test was performed three times, and we took the average results from those tests.
