SMTP Mail Sender is an application that allows you to send messages through an SMTP server. It lets you send messages if you do not have a mail application installed, or need to send from an account that is only used for sending messages without worrying about responses. It also runs from a USB thumb drive, so you can send emails from anywhere you have access to a computer with Internet access.
- Graphical user interface (GUI) instead of the run of the mill command line applications. UI allows customization by showing/hiding fields as necessary.
- If you need a true command line application that does not display a user interface, I highly recommend Blat.
- Built in address book saves you time typing email addresses, guesses and auto-completes addresses already in the address book
- Send messages using a SMTP server from any Internet connected computer from a thumb drive
- Supports attaching an unlimited amount of files to the message before sending
- Sends plain text messages to minimize bandwidth used for processing the messages as they travel across the Internet.
- Includes language support for English, French, Italian and Spanish
- Send messages automatically from a script using command line parameters. A GUI dialog will still pop up when automatically sending the message.

HI, great software! I need to know if is possible to add all the email address in the Address Book directly without selecting one by one. Thanks!
Hi Daniele,
Once you’ve added the first name to the address book so the file is created, you can edit the file with a simple text editor like Notepad. Just open the addbook.conf file with notepad and you’ll see the format. Basically it’s just:
Name <email@address>
Name 2 <email2@address>
You can add as many as you want there, and they’ll be loaded the next time you launch SMTP Mail Sender.
This was my first reply (via email): “Probably, due to my bad english, I didn’t explain well what I need. I had 100 email address in my address book, added from outlook, it was very easy to do. I’d like to know if I can add all these address as recipient when I compose a new message without insert one by one. Something like select recipients from address book. Thanks in advance”
And now, after the update I can say ALMOST PERFECT!
Only two things: the download links show version 1.0.0.16 but the correct one is 1.0.0.18 and I’ve a little problem with the gui, the envelope icon and the “Settings” button are cutted, while the new options is perfect.
I’ll send you a screenshot via email.
Thanks a lot

Hi Johan,
There aren’t any more log files, this is the only one. Those error messages you are receiving are coming directly from the mail server. The application just writes the error message to the file along with the time stamp. For Gmail, please try port 587 instead of 465. Gmail expects the full transaction to be encrypted on port 465, but it uses a feature called STARTTLS on 587 to accept email. SMTPMailSender uses some built-in .NET functions that do not fully support encryption of the entire connection, so each command is encrypted instead of sending plain text over a completely secure tunnel. Due to that, Gmail is expecting plain text and receiving an encrypted command.
I do not have any experience with Office 365. The first thing I’d try is to just disable SSL. I agree it’s hard to troubleshoot further when the remote server gives such a vague error, but there’s not much more SMTPMailSender can do other than report what it was told happened. I’m just speculating here, but is it possible that you’d need to enable SMTP access for your O365 account? Some webmail services do not allow submission of messages from remote hosts without prior authorization, to combat spamming.
Hopefully my thoughts will help you get SMTPMailSender working in your environment.
I can use it fine with my ISP smtp but doesn’t seem compatible with Gmail. I’ve tried it with 3 gmail accounts and it doesn’t send, gives error saying “syntax error: unrecoqnized command” in the log.
I’ve been using port 465 which Google says to use with SSL. So instead I gave 587 a try, and it worked. I’ve tried 465 using separate ISPs too. Perhaps its being blocked. Thanks for making such a useful tool, much appreciated.
This is a great software. Please when will you include the HTML formatted body functionality?
Jude,
There is no immediate plan to include HTML formatted body functionality. It is a simple tool for Windows systems that was designed to send one-off emails, mostly for reporting when processes complete. If you need capability such as HTML formatting, I suggest moving up to a standard email client like Mozilla Thunderbird. There are portable versions available, which will let you run it from a thumb drive, replicating most of the features in SMTP Mail Sender and then some.

Hey thank you very much!
Hal9000 has a great suggestion.
I’d like to add, can we use encryption inside or outside this fine app so we can sidestep any looking on my gmail?
IF so how?
Again thank you muchly!
JDough,
In regards to Hal9000’s suggestion, there are CC and BCC fields available for use in SMTP Mail Sender, and have been since version 1.0.0.10. If you do not see these in your version, you may need to download the latest version from this page.
As for encryption, you can enable SSL, but that only encrypts the traffic between your computer and the Gmail servers. Once it has completed that step, you have no further control over who does or does not see the message, that’s under the control of the email provider.
Hi All
Was just wondering if i can call this app through a batch file to populate some fields and send
Jason,
Yes it is possible to call the application via a batch file. Please check out the readme.txt file included with the release of the program. If you have not received the entire zip file including the readme file, grab the latest version from http://www.haztek-software.com/files/SMTPMailSender.zip.
What would really round it off would be a return code confirming a send or escape.
Nice little App, if only it worked for me…
Can someone tell me, why it won’t send my emails?! I’ve tried all sorts of servers, from Hotmail, Gmail, etc, and the Emails never arrive… Does it connect to a certain IP, that my IP Blocker might be Blocking?!
Ole,
If you are using Gmail, you will need to configure the application to use Google’s mail servers. There are instructions available on Google’s site on how to do this. https://support.google.com/a/answer/176600?hl=en
Your ISP may block outgoing mail on SMTP port 25. If that is the case, you will want to configure it to use port 465 and enable SSL. I’ve never tested with Hotmail, but I know that it will work with Gmail and Yahoo, as I’ve used both of those before (and still do).
