10 Reasons to Choose a Professional SMTP Service

Published on November 30, 2011 in Tips & tricks. 0 Comments Tags: , , .

Our users know very well that SendBlaster supports any SMTP servers in the world.
Standard (free) SMTP servers are good if you manage small email lists. For example Google Gmail allows sending up to 250 daily messages using its SMTP.

If you manage to send thousands of newsletters to your large email list through your standard SMTP server, they may never arrive in your recipients’ inboxes.  Why? Because Internet Service Providers (ISPs) often limit the number of messages a sender can send at once while also aggressively filtering incoming messages.  Dedicated SMTP servers solve these problems. Below are 10 compelling reasons to switch to a dedicated SMTP service provider:

  1. Improved Deliverability – ISPs do their part to eradicate spam by blacklisting IP addresses. Dedicated SMTP service providers work with major email providers to ensure that the dedicated SMTP server remains whitelisted.
  2. Easy Setup – Setting up a professional SMTP service is a simply matter of modifying your email client’s SMTP settings.
  3. Ease of Use – Sending thousands of messages in small batches to get around volume limits is tedious and time consuming. With a dedicated SMTP server, you can send thousands of bulk email messages with a single click from within your email client software.

The Legitimate Sender Challenge

Published on August 24, 2010 in Best Practices. 0 Comments Tags: , , , , .

Many legitimate senders face an increasing challenge of being designated as spam, even from their opt-in subscribers. People are being inundated with email and may inadvertently designate your emails as spam because they forgot that they have previously opted-in to receive your communications. In other cases, recipients may find it difficult to locate your unsubscribe link and simply find it easier to click the spam designation to remove you from their inbox.

For legitimate senders, it is important that you understand that subscriber behavior can be unpredictable and irrational at times. What was a conscious opt-in action one day can randomly turn into an unconscious spam action the next. The consequence of these actions is that it damages your IP reputation with the ISPs and if repeated, can lead to more drastic results that include delays, blocks and blacklisting.

Here are three best practices for senders to consider:

Free and Paid SMTP Services

Published on January 13, 2010 in Recommended links and Sendblaster. 1 Comment Tags: , , .

“What SMTP service do you suggest to use with SendBlaster?” This is a question that customers often ask us.
We continue to emphasize that good email marketing needs good SMTP service. In these times there is a wide choice of free SMTP services, offered by different ISPs, hosting companies and Webmail providers. The point is that they do not always perform well. Moreover they usually place a limit on the number of emails you can send within a certain time period and they can change their outbound email policy at any time without any prior notification.

If you send out small mailings and you are not concerned over poor performances they could represent a valid solution. If you do frequent or large mailings, and you find out that lots of messages being not delivered or filtered as spam, you should consider a dedicated third party SMTP service. It’s the best technical choice and, used with a desktop mailer as SendBlaster, is still much cheaper than any ESP. To meet these needs we have partnered with SMTP.com, the world’s oldest and most trusted email delivery provider, and created SendBlastersmtp.com. By using this professional service don’t have to guess whether your deliveries will go through. Configuration is easy and you’ll be able to get your mailing out no matter what the circumstance.

What Is Your Email Reputation?

Published on November 2, 2009 in Tools. 1 Comment Tags: , , , .

email reputation A good habit to follow before sending your bulk email is to look up the IP reputation of your SMTP service.
IP reputation is the major contributor to delivery rates, especially if you are sending to the largest ISP’s, e.g. Yahoo!, AOL, Hotmail. Statistics show that 83% of the time, sender reputation is the real cause of filtering: by monitoring it you will be able to identify problems affecting your sender reputation, determine the causes, and fix them.

Here are some of the major metrics ISPs look at when managing the message sent into their system:
- volume of emails (illegitimate bulk mail do normally trigger spam filters)
- spamtraps hits (old inboxes that ISPs reactivate specifically to trap spammers )
- invalid address rates (hard bounces)
- complaints rates (how often recipients hit the “report spam” button to response to your message)

The good news is that there are some online services that let you check your IP reputation. We recommend these four Free ones:

Do You Care About Bounces? Spammers Don’t

How many email addresses in your lists are invalid or not reachable?
Nowadays a clean list is a must.  If your list contains a significant number of invalid e-mail addresses, the ISPs may think you are trying to spam and stop delivering your e-mails.   Let’s see how to increase deliverability managing bounce-backs with SendBlaster.
First, let’s define them. There are two main types of bounce-backs:
Hard bounces: the e-mail message could not be delivered because the recipient’s address is invalid (domain name or host doesn’t exist, the recipient it unknown). These errors indicate a permanent problem.
Soft bounces: the email message reaches the recipient mail server but not the recipient (recipient’s mailbox is full, server is temporarily down, message is too long). These errors are generally temporary. Most email service providers will attempt to deliver the email message for a few days. If it is still undelivered, it becomes a hard bounce.

“This is spam” is not a substitute for “Unsubscribe”

Published on September 23, 2009 in Tips & tricks. 0 Comments Tags: , , .

According to a recent survey promoted by MarketingSherpa most consumers don’t correctly comprehend the term “spam”: 56% consider marketing messages from known senders to be spam if the message is “just not interesting to me.” But there’s more. Regarding the use of the “report spam” button – the primary tool that internet service providers (ISPs) provide readers to counter spam – nearly half of respondents (48%) provided a reason other than “did not sign up for email” for reporting an email as spam.
Confusion is pervasive among consumers regarding what they believe will happen as a result of clicking the “report spam” button:

* Over half of respondents, 56%, reported that it will “filter all email from that sender.”

* 21% said it will notify the sender that the recipient did not find that specific email useful so the sender will “do a better job of mailing me” in the future.

* 47% said they would be unsubscribed from the list by clicking “report spam,” whereas 53% do not think that’s the case.
