How to Pick Your Slack Integrations

Here are the steps you can follow to pick the best Slack integration for your needs, based on the type of team you have.

Step 1 – Think About Where Your Team Struggles Inside Slack

One of the best reasons to use Slack is to allow a large team to work together more efficiently. Having one messaging system to discuss projects, ask questions, or simply check on the progress of a subproject is a great reason to use Slack.

However, your team may struggle in a few areas with making the most of Slack’s features. Adding Slack integrations within your Slack channels further expands the usefulness of Slack.

This is especially important for larger teams. Larger teams that may work in remote locations and may have difficulty meeting in one place will appreciate Slack and many of the best Slack integrations.

Step 2 – Understand Your Budget Limitations

It’s easy to think that you need all of the best Slack integrations on our list and more. However, you likely will have to remain within a certain budget for your team, and most of these Slack integrations will cost extra money each month.

Prioritize the needs of your team for Slack integrations to ensure you’re spending your budget wisely. If you would love to be able to create polls within Slack, such as with Simple Poll, but you only will make a few polls a month, this integration probably isn’t worth the cost.

One of the best Slack integrations where you don’t have to worry about cost is with Google Drive. Its 15 GB free storage tier should work nicely for sharing files among Slack members, so you don’t have to worry about adding costs.

Step 3 – Focus on the Makeup of Your Team

Before your team can be productive and collaborative, team members need to trust each other and feel comfortable with each other. If you often need to bring new members onto the team, look for Slack integrations that can help team members learn to know each other.

Adding Donut to Slack is a great way to introduce new team members and allow them to begin contributing quickly. Donut also has a number of fun functions that help existing team members get to know each other better, encouraging trust.

Step 4 – Do Team Members Need Help With Collaboration?

For teams that struggle to collaborate effectively with Slack alone, adding integration with other apps hopefully can help them learn to collaborate better.

The integration makes it easier to share ideas using marked-up screenshots, allowing team members to work together to fix issues.

Simple Poll is another outstanding Slack integration that gives team members the ability to figure out the best way forward in a project. If you have team members who hesitate to speak up about their ideas, the anonymous nature of Simple Poll may help them feel comfortable introducing ideas.

Step 5 – Finding Help With Productivity

Slack can be a great productivity tool, but it becomes even better with the right Slack integrations.

For those teams already using Trello boards, adding Trello integration into Slack ensures all team members are constantly up to date with changes on Trello, enhancing their overall productivity. is another key productivity tool for Slack team members, as they always will know which people are on vacation or are not in the office, making the process of setting up in-person meetings or virtual meetings easier.

The Zapier Slack integration is probably the biggest potential aid to productivity. Zapier always ensures that the team members have the latest information showing up in Slack from all of the different apps they use. If team members can avoid becoming overwhelmed with the information they receive, Zapier should make them far more productive than with Slack alone.
