Return Path's Deliverability Report

Last week, our partner Return Path released their semiannual Global Email Deliverability Benchmark Report, covering the second half of 2011. There are a few interesting findings from this report which we'd like to share.

First of all, there was a noticeable decline in global inbox delivery. Previously, inbox delivery was stable at around 80%. However, that rate dropped to 76.5%.

This was likely caused by a combination of factors, including:
  • A spike in complaints and fluctuating volume during the busy holiday season.
  • Email overload. People are opting in to more newsletters and deals emails than ever before. Per Microsoft, 50% of inbox email is of this type.
  • ISPs are constantly adjusting their filtering rules.

We believe that JangoMail can help on all fronts:
  • We participate in complaint feedback loops with all of the major ISPs, which allow us to receive, process, and monitor complaint details. Our large pool of sending servers distributes spikes in volume to reduce deliverability issues.
  • Personalization features (even something as simple as greeting a recipient by name) can go a long way in recipients wanting to continue receiving your campaigns. It is also important to clearly state why the user is receiving the mailing.
  • We are constantly monitoring deliverability rates, and working with ISPs and our users to resolve any new issues that arise.

A figure involving complaints also stood out to us. 75% of Microsoft recipients use the "Report Junk" button, rather than an unsubscribe link, to remove themselves from mailings. As mentioned earlier, we receive these reports via the complaint feedback loop. However, a high complaint rate can cause delivery issues, so it is critical to have a clear, working unsubscribe link. Many email marketers are now also placing opt-in details and the unsubscribe link at the top of the message. This is a great way to lower the complaint rate.

Finally, for the best deliverability, we offer our customers whitelisting with Return Path. Those who meet the program requirements and are accepted have all their emails sent via Safe Senders. See our website for more information!

Calling the JangoMail API in Ruby Using SOAP

If you're integrating in a Ruby environment, then Savon is a great, versatile way to call SOAP web services. In this example, we use savon to build a soap client for the JangoMail API, then call Groups_GetList_String. To test it with your own account, just insert your own JangoMail/JangoSMTP credentials. Download the source code for this example to start your own integration!

# make sure to include savon for building soap requests
# see to download
require 'savon'

# first, build the soap client from the wsdl
client = 

# specify the xml for the request, inserting your credentials
response = client.request 
    "" do |soap|
  soap.xml = """<?xml version=\"1.0\" encoding=\"utf-8\"?>
    <soap12:Envelope xmlns:xsi=\"
    <Groups_GetList_String xmlns=\"\">
    <Username>Your JangoMail/JangoSMTP Username</Username>
    <Password>Your JangoMail/JangoSMTP Password</Password>
    <RowDelimiter> </RowDelimiter>
    <ColDelimiter> - </ColDelimiter>

Be a Safe Sender: JangoMail's Return Path Certification Program

One of JangoMail's deliverability tools is a third party whitelisting program, offered in partnership with Return Path. The Return Path Certification program is a great way to improve deliverability, and JangoMail customers who engage in good email practices and want to improve inbox delivery rates should consider applying for the program.

Return Path recently made some changes to its Certification program, so in this post, we'll overview the program offerings and benefits for new users and update existing Certified members on the changes to the program.

Program Overview:
The Return Path Certification program distinguishes legitimate emails from spam to make sure legitimate commercial emails aren't inadvertently caught in spam filters. Over 50,000 ISPs, universities, and organizations around the world, including MSN, Hotmail, and Roadrunner, use Return Path's whitelists. If you've ever worried about your emails ending up in junk-mail boxes, being a Return Path Safe Sender can help. JangoMail is a certified reseller of the Return Path Certification program, so existing JangoMail customers are eligible to apply for and participate in the program. Acceptance into the program is based on adherence to Return Path’s high standards.

What are the benefits?   
To put it simply, increased deliverability and higher open rates. If you're accepted into the program, then all emails sent from your account will be sent from special servers that are whitelisted with Return Path. These servers are designated exclusively for JangoMail customers participating in the Return Path program. The main benefit is improved deliverability. Emails sent from Return Path servers have a much smaller chance of being flagged as spam, and this increased inbox delivery can boosts your open rates significantly. A recent Return Path case study revealed that participation in the program yielded a 15% increase in email open rates for Internet media giant CNET.

How does it work?
Email senders and receivers participate in the certification program. Return Path maintains a whitelist of outgoing IP addresses that have been accepted in the program and thus designated as Safe Senders. Email receivers, such as ISPs and corporate domains, then use this list to help them identify legitimate email. If you meet Return Path's standards and are accepted into their program, your outgoing email IP address is added to this Safe List, resulting in higher delivery rates for your emails.

Two levels of whitelisting:
Return Path now offers two levels of whitelisting services: the Safe List and the Certified List. Both levels result in improved deliverability and open rates by including sending IPs on the Return Path whitelists.

The Safe List: The first level of whitelisting offered by Return Path is inclusion on their Safe List, which designates you as a "Safe Sender." As a Safe Sender, you get preferential treatment with spam filters so that your legitimate permission-based messages aren't filtered into spam folders. Inclusion on the Safe List marks you as a legitimate business enterprise that follows best practices and uses well-configured, authenticated servers. The primary benefit of being on the Safe List is preferential treatment with spam filtering mechanisms like SpamAssassin. For example, when SpamAssassin, the world's most popular spam filter, recognizes a Safe Sender, it automatically lowers the email's spam score, thus increasing the likelihood that your email gets to the inbox.

JangoMail customers sending through our shared IP pool are eligible to be included on the Safe List. To join this program, you can apply directly to JangoMail.

The Certified List: The second level of whitelisting offered by Return Path is inclusion on their Certified List. Acceptance into this program designates you as a Certified Sender and offers a higher level of whitelisting; it designates you as a sender who measures up to the very best standards and provides preferential treatment at a large number of ESPs. Though the specific perks vary between ESPs, benefits include ensured inbox delivery at Hotmail and automatic enabling of links and images at Yahoo.

To be eligible for the Certified List, you must send from dedicated IP addresses (i.e. not a shared IPs), have been sending from the dedicated IPs for at least 90 days, and pass an audit of your email practices. Applications for this program must be made with Return Path itself.

A Note on Changes: Customers currently participating in the Return Path program will note that this represents a change from the now-discontinued Certification program. Participants in that program are eligible to apply for either of the new offerings. Note, however, that the participation in the new Certified List requires you to send from dedicated IPs, rather than shared IPs acceptable in the previous program. If you're interested in sending from a dedicated IP address, contact us and we'll help you get set up.

Interested in learning more?    
If you're interested in learning more about the program or applying for Safe Sender or Certified Sender status, let us know. Full details about the program, application process, and associated fees are available on our website. You can also visit the official Return Path Certification website to learn more. As always, contact us if you have any questions, and our support team will be happy to help.

Calling the JangoMail Web Service in Python

Python is a language that seems to make so many mundane programming tasks easy. Unfortunately, some python libraries are perhaps less fully developed than the libraries of other languages. This is certainly the case of the python soap libraries SOAPpy and SUDS. In my experience, both libraries are painfully buggy. In python, I think it's easier just to use httplib and build the xml manually. Luckily, python's other conveniences make that pretty easy!

In this example, we build an xml template for calling Groups_GetList_String. To test it with your own account, just insert your own JangoMail/JangoSMTP credentials. Download the source code for this example to start your own integration!

import sys
import httplib

# setup the sml template xml for a call to Groups_GetList_String
SM_TEMPLATE = """<?xml version="1.0" encoding="utf-8"?>
    <Groups_GetList_String xmlns="">

# fill in the parameters for our call
SoapMessage = SM_TEMPLATE%("Your JangoMail/JangoSMTP Username", 
              "Your Password", "\n", " - ", "")

# examine the soap message that we have constructed
print SoapMessage

# insert the proper values into the header
webservice = httplib.HTTP("")
webservice.putrequest("POST", "/api.asmx")
webservice.putheader("Host", "")
webservice.putheader("User-Agent", "Python post")
    "application/soap+xml; charset=\"UTF-8\"")
webservice.putheader("Content-length", "%d" % len(SoapMessage))

# get the response and print it
statuscode, statusmessage, header = webservice.getreply()
print "Response: ", statuscode, statusmessage
print "headers: ", header
res = webservice.getfile().read()
print res

Consuming the JangoMail API in ASP.Net

It's easy to start integrating the JangoMail API into your company's .Net software. Start by adding a service reference to your project. Right click on the project in the solution explorer, then click "Add a Service Reference". Under Address, enter and click "Go". Then change the namespace to JangoMail and click "OK". This will add the files necessary to reference the JangoMail web service within your application or website. Then you can call all the JangoMail/JangoSMTP API methods from within your software.

In this two line example, a JangoMailSoapClient object is created, then used to invoke the method that gets a list of the email lists on your account. Download the source code for this example then start your own integration!

// first create the JangoMail soap client object
JangoMail.JangoMailSoapClient j = 
    new JangoMail.JangoMailSoapClient("JangoMailSoap");

// then call the getlist method and display the results
Result.InnerHtml = 
    j.Groups_GetList_String("Your JangoMail/JangoSMTP Username", 
                            "Your JangoMail/JangoSMTP Password", 
                            "<br/>", " - ", "");

How to select images for your marketing material

Guest post from Fotolia, a leading provider of royalty-free images.

Adding visual appeal to all kinds of material from campaigns to blogs to newsletters grabs the audience’s attention. That’s why marketing professionals rely on imagery to enhance their campaigns and overall messaging strategy.

Here are 5 tips to help you select the perfect fit for that added, and much deserved, side of “visual punch”.

Rule # 1: Use your image to communicate
A picture is worth a thousand words, and is indeed a clever and fun way to help your content speak volumes. The right image will not only complement what you have to say, but the message you want to deliver. Keep in mind that you want your image to make a statement. Choose one that is unique and specific to the feel and tone of your content.

Rule # 2: Be bold
This is your opportunity to think outside the box. Avoid taking the easy route of choosing an image that has a direct correlation with your topic. Consider other angles. There are millions upon millions of royalty-free images available to you, so have fun with your image browsing and dare to be different.

Rule# 3: People like to look at people
Consider using images that feature people as an effective way to reach your audience. Studies show that one of the reasons Facebook is such a hit is because of people’s fascination with looking at other individuals. For the most part, human beings feel a need to relate to others.

Rule # 4: Mind your colors & contrast
Aside from selecting an image that suits your overall theme and message, pay attention to colors and contrast – they’re both very important key factors in conveying the “wow” appeal you’re aiming for. The colors delivered in your image should complement the remainder of your content, including font styles and other colors that you may be using.

Rule # 5: Customize
This is where you can have the most fun with your images, stand out from the competition and be unique. Who’s to say that all you see is all you get? Modify your image to suit your needs, as long as you have the rights to do so. Turn your image into something that completely embodies what you want to communicate. The avenues for creativity are limitless and you better believe no one else will have an image like yours.
