How can I add to SendBlaster new contacts subscriptions?
Emails arrived to your management email, that contain the word ”Subscribe” inside the subject field will be automatically added to SendBlaster bulk email software when you hit the button “download subscriptions”
SendBlaster can gather new subscriptions from each email contained in a mailbox if the email has the word “subscribe” into the email subject field.
To automatic download new mailing list subscriptions inside SendBlaster Bulk Emailer you will have to set into SendBlaster your Management mailbox. This is called Management Email and will require username and password because SendBlaster will connect to that mailbox and download the email messages.
SendBlaster works with every existent mailbox, so the SendBlaster Bulk emailing system is compatible with every email or subscription system that can send an email with a specified subject. For example if you put this code into your webpages the subscriptions arrived to mailbox@testsendblaster.com will be added into SendBlaster:
<a href=”mailto:mailbox@testsendblaster.com?Subject=Subscribe” mce_href=”mailto:mailbox@testsendblaster.com?Subject=Subscribe”>Sign up</a>

You can also add to your website free modules to send subscriptions and gather user’s personal details:
The “Socket operation on a non-socket” error means that, for some reason, the Windows TCP-IP stack has been overloaded, and the socket channel (which is used for communicating with the Internet) has been shut down abruptly.
This error may have a lot of causes, which usually require a good network analysis and networking skills in order to be tracked down. But most of the times this is just a temporary error which will be solved simply restarting Windows.
If the error repeats, here are some hints:
- Before launching a mailing close all other programs and processes, expecially those who need internet access
- Temporarily disable your firewall, antivirus and other Internet security programs
- As a test, in order to track down timing problems on the network, configure SendBlaster’s “Send” settings to use just 1 connection and set a pause of 5 seconds between messages (if it works, you will gradually increase speed later)
- Perform a system scan and make sure that no spywares, trojans or other malware are running (they may be silently having Internet access)
- Update drivers for all network gear (modems, routers, USB dongles)
- If you are on a wireless connection, make sure the connection is good and stable
- Apply Windows updates if any are available
- If you are using an Smtp server, check that it is working (you may have to ask your ISP)
- As a last resort, install SendBlaster on another PC connected to the same local network (this way you will be able to check whether the issue is coming from your PC or from the network)
As this is a network-related problem, you may find additional information performing a search on a search engine with “socket operation on a non-socket” keywords.

When you compose your email message in SendBlaster, insert images by using “Image” button instead of using copy/paste; make sure they don’t have any “strange” characters in their name or path.
Another option would be creating the email template as an html page and then importing it into SendBlaster bulk email software template engine.
We always suggest to put a html link in your mailings, pointing to a remote image on your webserver, here’s an example:
1.000 email x 100kb each one means a total of 100 MB of data to send, that means that your isp may block you in sending such ammount of data.
You can also use SendBlaster as a software for sending HTML emails, text only emails and hybrid emails.
Sure; use servername:port format. As an example, if you want to use “smtp.provider.com” on port 579,
simply enter smtp.provider.com:579 as your Smtp server address.
f no port is specified, default port (25) is used for Smtp connections.
