When emails go missing in email purgatory, it’s time to reboot your ex-employee engagement strategy. A multi-channel effort—taking advantage of multiple media and tailored tactics—can pierce digital noise and create long-term bonds. This is an end-to-end best practices guide to ex-employee engagement with more than email, from tested-and-proven alumni and corporate engagement best practices.

What is Multi-Channel Approach ?

Multi-channel strategy is a method that aims to engage and reach your audience through various communication channels-both online and offline-instead of relying on only one like email. This method considers that people have varying preferences for how they interact with brands or organizations, whether it’s social media, chat apps, direct mail, company websites, or even live events.

By using more than one channel, you are more likely to reach your audience where they are most comfortable and open to receiving your messages, making the chances of your messages being watched and acted upon38. A multi-channel strategy really boils down to offering choice, making your outreach adaptable, and meeting people where they are most comfortable on channels that suit them in order to build stronger, leaner relationships.

Why Multi-Channel Engagement is Important?

Email isn’t enough alone: With bulging inboxes and dwindling attention spans, using only email is playing with fire and leaving you at risk of being overlooked by your recipient.

Ex-employees are an asset: They are potential brand representatives, referral bases, mentors, and rehire sources.

Relevance and individualization fuel engagement: Making your interaction personalized to individual interests and behavior ensures the highest probability of relevant interaction.
