Sendblaster 3 and Sendblaster 4 Review – Stand Alone Email Sending Software

Sendblaster 3 is the original version and Sendblaster 4 is the latest version of bulk email sending software from Sendblaster Inc. that is located downtown Sardinia, Italy. They also have offices in Milan, Italy.

Regardless of the size of the email contact list, it doesn’t take long for a tech-savvy business to figure out that its much better to send out their own marketing emails than using Email Service Providers (ESP’s) like Constant Contact, Vertical Response, Madmimi, Mailchimp and Campaigner. These services exist for small businesses that are not tech savvy, or are just too lazy to learn. Businesses not only pay for the privilege of using an ESP, but are also likely to damage their brand using one of these services, but are not savvy enough to realize it. You never see a large business using an ESP, so there is no reason why a small business should use them either.

Sending Email Using Sendblaster 3:

Sending marketing email using Sendblaster (or any other local email software product) gets increased email marketing functionality for the small business and it will cost a tenth of the price of the various offerings from the current ESP’s. The ESP’s do, however, make sending marketing emails quite easy, but fail to provide basic functions that every company would want to use. Many of the features that marketing departments need today are A/B Testing, re-sending to the recently-added-contacts on a marketing list, management of mis-spellings (It is obvious to us humans that yhoo.com should be yahoo.com, but not to Constant Contact), controlled delivery rate, controlled or random distribution and virus control.

Cost is also a very important  factor, with Constant contact costing $100  a month to house just 10,000 contacts but sending your own email can end up costing just $250 a year. Another unsettling control that the ESP’s put upon their users is the refusal to provide key data about contacts owned by the businesses, EG Constant Contact will not tell companies who made a spam complaint against them, citing the Can Spam Act of 2003, but in reality the Can Spam Act mentions no such thing about withholding the source of a complaint – its a self imposed policy using the Can Spam Act as cover, businesses want to know where they are having problems, but Constant Contact will just remove the contact from the list, never-to-be-mentioned again. Although the business’s contact data, Constant Contact actually owns the data when its on their servers. ESP’s have such large meta-data tables that they are  able to tell what email addresses are actually spam traps, but they will not actually tell their customers. ESP’s have contracts with market intelligence companies and provide cross sectional analysis for them – IE, they wont give the email address to them, but if asked they will tell the market intelligence companies what lists that they contacts are actually on. This is not  a practice  that a business partner should be doing and businesses leave ESP’s when they realize that the whole ESP business is somewhat corrupt. The most common ESP’s are Constant Contact, MailChimp, Vertical Response and Campaigner.com‎, and they are all in the racket.

Full Review Of The Sendblaster 3 Email Software

Advantages of Sending Your Own Marketing Emails:

  1. Dedicated IP Address:
     – You manage your own IP address. Your work to protect it getting whitelisted and staying whitelisted and never sending spam.
    – ESP’s all use shared IP addresses, so any idiot who buys a mailing list can instantly destroy the credibility of everyone else using that service, this is a common problem for Constant Contact and given the amount of money that you spend with them you shouldn’t have to experience these kind of outages, of which they have many.
  2. Manage Your Own Destiny:
    – You have ultimate control over your email server. You decide what goes out when and can schedule a time when the server isn’t getting overwhelmed with other people’s email sends
  3. You Can Send From Your Own Domain Name
    – Surprisingly, some ESP’s still make you send from their subdomain which looks terrible on an email, like you are a reprobate. The format is from X on behalf of  Y – X being the ESP and Y being your company. This is such an antiquated way of sending email and it does untold damage to your brand, so avoid at all costs.

Finding The Right Email Sending Software:

Once a business has decided that it can do a better job than than the ESP’s (email service providers) it’s time to find some email software that can send it. This can be a tricky task as there are many products out there and cursory reviews don’t indicate what problems you will have later down the line. For Example, we originally tested Atomic Mail Sender (AMS) as it has some nice functions for sending marketing emails, its also cheap and fast. In fact it works very fast, faster than any other similar product. But once you get into the meat of this product and start sending more then 30,000 emails out your IP address will be banned from cbl.abuseat.org, one of the most important spam detection services out there. During our testing and constant red flagging by cbl.abuseat.org, it became clear that the Atomic Mail Sender (AMS) is mostly used by spammers and leaves a certain signature during an email handshake, which cbl.abuseat.org spots and blacklists the IP address and sometimes the whole class B range. Regardless of whether the email is spam or not, it is these kinds of situations that a networking engineer can find himself in after spending considerable amount of time researching a product, only to find that it is in fact a dead end with his choice of email sending software.

Sendblaster 3 Review – Pro’s and Cons:

Pro’s

  1. Works well with various Message Transfer Agents (MTA’s)
  2. Great proprietary tracking software with open rate and click rate tracking
  3. Good integration with Google Analytics
  4. Good technical support, with a knowledgeable chat person usually readily available during business hours

Cons

  1. The GUI is MFI (made for idiots) which can frustrate seasoned professionals who know exactly what they want to do, but are restricted by the poor GUI
  2. The application often cannot handle symbols like quotation marks ” and copyright symbols ©, even though the data character set does support it. It replaces them with question marks ?
  3. During email editing, Sendblaster cannot perform a “find” for text in HTML or text formats. You cannot search for anything inside your emails during editing.
  4. A/B or Split testing is not available in Sendblaster. Nor can you run two sessions of the product up at the same time to get around the problem. Although you can buy another copy and put it on another server, bu this is a pain,
  5. Sendblaster is not suitable for email sends of 10,000 or more – Terrible speed drop-off after 10,000 emails, see the report below:

Sendblaster 3 Slows Down To  A Crawl During A Send Bigger Than 10,000 Emails:

sendblaster 3 email speed testingThe biggest problem with  Sendblaster 3 is the fact that during an email send, Sendblaster 3 will slow down to  crawl, the more emails you send. We removed all back end MTA impediments during the tests to determine that the delay is coming directly from the poorly written Sendblaster code

At the start of the email send, Sendblaster is quite a promising, with  speeds at 1500 emails per minute. After a few thousand emails are sent, the speed starts coming down to 600 a minute and a little further in to the email send things get very bad.  Sendblaster reaches a maximum speed of just 250 emails per minute when it reaches 30,000 email sent, which is a maximum of 15,000 emails per hour, which is pretty poor performance for an email sender software.  It will continue at this speed indefinitely and this is undeniably a very slow rate for email sender software. The database behind Sendblaster 3 must be using MSAccess or something equally slow, as it appears to chug slower and slower, reminiscent of a badly written MS Access macro, that does not leverage the Rushmore technology that Fox Software brought to Microsoft with the Fox Software Acquisition in 1992, that was quickly folded into MS Product line including Visual Fox. It seems that Sendblaster 3 is not leveraging any of that technology, that is now decades old and it needs to be updated.

For the technically inclined, in our tests we removed all  factors that could be causing latency such as email tracking, slow processor speed (replaced the processor with Intel® Core i7 quad-core), memory (we replaced with 64GB), removed all other applications/ virus checkers etc, we replaced the hard drive with a samsung EVO SSD and ported the email directly into a dummy file, instead of the MTA that we had been using for testing, which in this case was PowerMTA and that can handle way above 10,000 emails a second. Although we left no stone unturned, all evidence points towards the SB3 product being greatly disadvantaged by speed and entirely unsuitable for email sends larger than 10,000. This makes the application great as tool for businesses with less than 10,000 contacts, but troublesome for any business that has more and needs to get emails out quickly.

Work-Around Solution For The 10,000 Problem:

To get around the problems that Sendblaster 3 faces with latency, it is suggested to divide up the email-send into blocks that are less than 10,000 contacts each. We tested this hypothesis and sure enough, it does work. It gets decent speeds at sending and we never have to deal with the 10,000+ slowness problems that we have seen in our tests. Obviously, dividing your list up into many small sections and sending each one invidually( and waiting for it to finish, as you cannot schedule them one after the other) is an annoying pain and increases the risk that you might forget to do a send or accidentally send the email twice. Removing the risk of human error is always a good approach for any system, but Sendblaster’s limitations and resultant work-around actually introduces new human error, rather than reduce it.

Sendblaster 4

The guts of Sendblaster 4 are almost identical to Sendblaster 3. All the known bugs and issues remain in the new version. What has changed are in Sendblaster 4 is that the GUI is a lot cleaner and easier to use.
