Put on your marketing hat and plan out a full-scale communication campaign to encourage text message opt-ins, well in advance of your first text campaign.
Give employees time to process the message. Not everyone will remember if they only see one email about it, but if you remind them several times in multiple different locations, it’ll stay top-of-mind for them and they’ll be much more likely to get around to it.
Provide a deadline and create a sense of urgency for them to opt in before that date. Whether it’s positive reinforcement with an incentive or negative reinforcement with a consequence, having a hard deadline to go along with your opt-in instructions will help make the message crystal clear.
Hold at least two company-wide meetings where you introduce the new communication method and ask everyone to pull out their phones and opt in right then. Then send out a recording of the meeting with opt-in instructions afterwards to catch anyone who wasn’t able to attend.
Use personalization and eye-catching subject lines in your email campaign to ensure that people open them. In addition to a specific email campaign encouraging opt-ins, include opt-in details within your weekly email newsletter and any other HR emails for several weeks in a row before the deadline.
If employees are still heading into the office, put up flyers with quick and easy opt-in instructions in high-traffic areas so they’ll receive a visual reminder on a regular basis.
