@Timur Right! As a rule, more personal = more effective, no matter what kind of campaign we're running or what channel we're talking about: email, SMS, direct mail, whatever. I like your example for a couple reasons:
- First, I think you're smart to do initial outreach that is *giving* something, not *asking for* something. Customer relationships seem to have a half-life: The more time passes since their last purchase or interaction, the more tenuous the relationship becomes. In your example, assuming your campaign evolves towards requesting a review, you're first creating a fresh experience for the customer to consider: "This company came out to fix my fridge last year and they still check in on how I'm doing!" It conveys caring.
- In SMS especially, that higher level of personalization establishes trust. One powerful thing about SMS is that almost all of your customers will see/read at least your first message. But if you're not regularly in touch with these customers, messaging them out of the blue risks a "Who dis?" response, haha. However, you have enough specifics in there to hopefully jog the customer's memory and demonstrate right away that the message is legit.
This kind of campaign will be more tedious to implement than a less personalized campaign, but still doable at 1.5k contacts even if there is a manual component. And, if you ask me, the work is worth it. Your customer list is finite and you want to get max value out of it because you can't go out and buy another. Every customer counts.
You'll probably want to think in terms of templatizing your messages and what data you'd need to fill those templates: "hey {{firstName}}, we serviced your {{applianceMake}} {{applianceType}} back on {{lastServiceDate}} and we would like to remind you 5 tips to keep your {{applianceType}} in good shape..." If you can assemble a spreadsheet of customers with this info, you can execute this campaign.
Obviously, you'll also need to plan for a sequence of messages or an additional campaign to make the review ask.
Honestly, I don't know that a dedicated review management software is necessarily what you need for this. My impression is that many businesses have shifted towards broader business comms and CRM tools that allow them to do review-gen and also a whole lot more.
