Rumors of email’s demise have been greatly exaggerated. While the “age-old” communication conduit may have new rivals, it is showing little sign of letting up.

In 2017, active email users stood at 3.7 billion globally, a figure that’s expected to hit 4.1 billion by 2021, according to research firm Radicati. Last year, nearly 270 million emails were sent each day, and this is expected to grow 4.5 percent to 280 million in 2018. Messaging and VoIP apps may be popular, but email still has a crucial role to play, particularly in longer-form communications and in the B2B and B2C realm.

SendGrid, a well-funded email delivery performance platform, went public on the New York Stock Exchange (NYSE) in November at $16 per share, and its shares have been riding at around 75 percent over its IPO price in the months since.

Venture capitalists continue to bet on email startups, as well. Front recently raised $66 million from big-name backers such as Sequoia and DFJ to grow its email collaboration platform, while Sigstr raised $5 million for a tool that lets companies transform email signatures into advertisements.

Elsewhere, Google gave Gmail a major upgrade a few weeks back with a big focus on security and productivity, while at its I/O developers conference this week the company announced a new AI-powered Smart Compose feature for faster emailing. Microsoft followed suit with a bunch of new features for Outlook.
