  • New user interface

    SendBlaster 4 has undergone the most important UI redesign ever. The new, flat UI looks modern and cool, and everything is easier to use on touch screens.

  • New HTML engine

    SendBlaster 4 uses a greatly improved HTML engine. Not only is its rendering of HTML better, but the output code is also more polished and conforming to modern standards; the visual editor better preserves the original HTML code.

  • Segments

    SendBlaster Pro 4 allows creating list segments (subgroups) based on multiple rules; this makes organizing and maintaining lists much easier. You can now optionally send out to a list segment only.

  • Unsubscribe replicator

    If you manage multiple lists, and they share some contacts, you may end up having a given contact marked as unsubscribed in a list, but still flagged as subscribed in a different one. If this is not desired in your scenario, Unsubscribe Replicator propagates unsubscriptions from any list to the other ones: if a contact is “unsubscribed” in ANY list, it will be marked as unsubscribed in ALL lists.

  • Adjust images in place

    The visual editor includes an inline photo tool which lets you apply the most common and useful filters and effects to images on the fly and in place. You don’t need to export images, process them with external utilities and then add them back to your message: just select an image in the message, edit it, and immediately see the results.

  • Follow up mailings

    All contacts which were included in a previous mailing can be selectively enabled in the current list. This way, you can send a followup mailing only to those who already received a specific one.

  • Database maintenance

    SendBlaster 4 includes a fully integrated database tool for periodically optimizing the size and performance of your database.

  • Integration with MailStyler

    MailStyler is a powerful newsletter design software, which lets users design cross-client compatible and responsive emails with a simple drag and drop editor. When you select “MailStyler” as your new message type, SendBlaster launches MailStyler (if it’s installed), and waits for it to be shut down; it then automatically loads the last message you exported from MailStyler.


More features


  • Add calendar events to your message

    Make your mailings more effective and make it easier for your contacts to remember your offers and events: with SendBlaster Pro 4 you can create an event and add it to your mail as an iCalendar attachment; when recipients click on the attachment, the event will be added to their calendar.

  • JotForm integration

    JotForm is a popular platform for designing beautiful forms, fully integrated with all major content management and shopping systems. SendBlaster 4 allows you to easily import subscriptions and cancellations from your JotForm account by just entering your credentials.

  • More speed

    SendBlaster 4 now supports up to 100 connections – on a high-end platform, this could dramatically improve the speed of mailings when using a fast remote SMTP server or a local one.

  • Optional HTML “source editing only” mode

    With SendBlaster 4, experienced HTML designers can optionally do without the visual editing completely and retain full control of their source code.

  • Mail to new contacts

    All contacts which were included in a previous mailing can be selectively disabled in the current list. This way, you can send a mailing only to those who didn’t receive it yet.

  • Save relevant incoming emails locally

    Antispam rules require you to keep long term proof of your subscriptions: SendBlaster 4 helps you in doing so by saving subscription emails locally. You can save cancellations and bounces too for future reference.

  • 1×1 Pixels Tracking

    TrackReports code can now optionally use a 1×1 pixels tracking image, making the tracking more unintrusive than with previous releases.

  • Improvements and new options

    SendBlaster 4 engine underwent lots of internal enhancements and optimizations in order to increase speed, performance and robustness, and many options were added to common operations.

  • New templates

    SendBlaster 4 comes with 60 brand new responsive templates, totalling 150 templates in Free edition and 230 in Pro edition.
