InstaMailer

InstaMailer is a lightweight and very simple-to-use piece of kit that enables you to quickly send emails via Gmail or Hotmail accounts, without going through the trouble of an all-round email client or navigating online to the providers' websites.

Portability perks

Since installation is not required, you can drop the program files to any part of the hard disk and just click the executable to run. Another possibility is to save InstaMailer to a USB flash disk or other mass storage device, in order to run it on any PC effortlessly and quickly send emails.
An important factor worth keeping in mind is that the Windows registry and Start menu do not get updated with new entries, and no extra files are created on the HDD, leaving it clean after removal.

Simple interface and options

The GUI is represented by a regular window with a neatly organized layout, providing quick access to all available options. You can get started by selecting the type of account between Gmail and Hotmail.

Easily configure email settings

Apart from inputting the sender email address and password, all you have to do is specify the receiver address, mail subject and message. If needed, you can also modify the default SMTP server and port number. Settings can be restored to default with the click of a button.

Evaluation and conclusion

We have not come across any issues in our testing, since InstaMailer did not hang, crash or pop up errors messages; everything worked smoothly. The tool is very responsive to commands, sends messages rapidly and remains light on the system resources.
In conclusion, if you're looking for a fast and effective method to send email messages without worrying about advanced features (e.g. HTML formatting, attachments), then you should definitely look into InstaMailer.
