In today's digital workspace, an email can create just as powerful an impression as a handshake or introduction.

However, not all of us are graced with the writing acumen to send off eloquent, grammatically perfect correspondence on our own. Thankfully, we don't have to be with WhiteSmoke Premium.

This intelligent all-in-one spelling/grammar app helps you send off pristine correspondence with minimal effort, and lifetime subscriptions are on sale today for 82 percent off the usual price.

A great solution for checking English grammar, style, spelling, and punctuation, WhiteSmoke uses unique, patented artificial intelligence algorithms to check your work for errors, whether you're writing on mobile or desktop.

It's compatible with most browsers and even includes a translator for over 50 languages. Plus, WhiteSmoke can even work with Word and Outlook to proofread your emails and documents.

WhiteSmoke Premium activates with just one click in browser-based text editors and features a database for checking against plagiarism - handy when you're working on that last-minute term paper.

And, with a lifetime subscription, you'll get access to all current and future product features for free, for life, so you can keep sending perfect correspondence well into the future.

With WhiteSmoke Premium in your corner, you can trust that your correspondence is presentable and you'll refine your writing skills as you use it.

A lifetime subscription to WhiteSmoke Premium normally retails for US$399.95, but you can sign up today for only US$69, saving more than 80 percent off the usual price.

But if you're not quite ready to commit to a full plan, you can also sign up for a 1-year subscription, on sale for US$19.99.
