Slack will increase its prices in September, in addition to some major changes to its free plan. It is the first price increase since Slack launched in 2014, but will only affect users of Slack’s “Pro” plan. On 1 Sept. monthly Pro subscriptions will increase from $8 to $8.75 per user per month, and annual Pro plans are increased from $6.67 to $7.25 per user per month.
The price increases only affects Pro customers worldwide, not companies running Slack’s Business Plus or custom business plans. However, there is a way to avoid the price hikes for another year. Current annual Pro subscribers can lock in the existing annual rate for another year by renewing their subscription early before September 1. Monthly Pro subscribers can also switch to the annual rate before September 1 and keep the existing rate of $6.67 per user per month for one year.

Slack is also making some big changes to its free plan. Currently, free Slack servers show the last 10,000 messages and up to 5 GB of uploaded content. Starting September 1, Slack will change this to show the last 90 days of messages and uploads, with no limit on the number of messages sent or the amount of content uploaded. “The majority of our active free teams can access more of their message history with the new 90-day limit compared to the previous limit,” explains Slack in a blog post. “No matter how much your free team uses Slack, you always have access to 90 days of history.”
Slack’s free users also get access to the Clips feature that allows users to send audio, video, and screen share messages in channels and DMs. Free teams can now also set a retention period for their messages and files starting September 1.
