The Tuesday morning I opened Gmail to 140 unread Takealot messages
Load-shedding hit stage four at 6 a.m. I'd plugged my router into the inverter but forgotten the kettle, so I was drinking instant coffee mixed with cold tap water when I opened Gmail and saw the counter: 140 unread messages, all from Takealot's seller portal. Returns, refund requests, shipping complaints, one person who'd sent nine emails in a row asking why their order hadn't moved in three days. I run a Shopify store that sells kitchen gadgets and small appliances—mostly to Johannesburg and Cape Town—and I'd connected it to Takealot's marketplace two months earlier. Sales doubled. Email also doubled, then tripled, then became this.
I had four hours of power left on the inverter. I could spend it writing the same six replies over and over, or I could try the Auto routing feature in Kryotta that I'd been ignoring since I signed up. Auto routing picks which AI model answers each query based on what the query actually needs: a fast cheap model for simple stuff, a bigger one for anything complicated. I didn't know if it would work. I also didn't have a better plan.
What Auto routing actually did with the first twenty emails
I connected my Gmail to Kryotta through the connector—took ninety seconds, two OAuth clicks—and dumped the first twenty emails into a new thread. I turned on Auto routing and wrote one prompt: "Draft a reply to this return request. Approve refunds under R500 if the reason is defect or wrong item. For shipping delays, apologize and give the current courier tracking status. For complaints about product quality, ask for a photo and order number. Keep it polite and under three sentences."
Auto routing sent the first email to Amazon Nova Micro. The email was someone asking if we accepted returns after thirty days. Nova Micro said no, cited our policy, done. Cost: a fraction of a cent. The second email was a refund request for a R1,200 blender that arrived with a cracked jug. Auto routing bumped it to Claude Haiku 4.5—more expensive, better at judgment calls. Haiku approved the refund, drafted a reply with an apology and return instructions, and flagged it for me to review because the amount was over my R500 threshold. I checked it, sent it, moved on.
By email twenty I'd seen Nova Micro handle twelve simple queries, Haiku take six that needed some reasoning, and Gemini Flash pick up two that had attachments—photos of damaged goods—because Flash is faster with images. The total cost so far was R1.80. A VA would charge me R150 an hour, and I was twenty minutes in.
The refund approval that Auto routing got wrong
Email forty-three was a return request for a R480 air fryer. The customer said it "smelled like burning plastic" after ten minutes of use. My prompt said approve refunds under R500 for defects, so Auto routing sent it to Haiku, Haiku approved it, and I almost clicked send. Then I read the original order notes. The customer had bought the air fryer six weeks earlier, used it heavily—judging by a follow-up email thanking us for fast delivery—and now wanted a refund three days after the return window closed. The burning smell might be real. It might also be buyer's remorse plus a convenient excuse.
Haiku didn't catch that because I hadn't told it to check the order date against the return policy. I added a line to the prompt: "If the order is older than thirty days, flag for manual review instead of auto-approving." I marked the email for follow-up, asked the customer for a photo and the purchase date, and kept going. Auto routing saved me time. It didn't save me from writing a bad prompt.
Load-shedding killed the inverter at email seventy-one
Stage four ended at 10 a.m. Stage five started at 10:04. The inverter beeped twice and died. My laptop had forty minutes of battery left, the router was gone, and I had sixty-nine emails to go. I tethered my phone, watched the data counter climb, and kept working. Auto routing didn't care that I was on a 4G connection instead of fiber. It also didn't slow down, which was a problem—every model call was now chewing through my monthly data cap. I switched off the Gmail connector sync so it wouldn't pull new messages in the background, worked through the queue, and finished at 11:30 with twelve percent battery and 1.8 GB of data used.
The rand cost of the AI calls was R28 for all seventy-one emails. The data cost was another R90 because I'm on a Vodacom prepaid plan that charges R0.05 per MB after the bundle runs out. Total: R118. A VA would have charged R300 for two hours of work, assuming I could find one available on four hours' notice during load-shedding. The math worked, but only barely, and only because I stopped the sync before it ate the rest of my data.
Which model Auto routing picked for angry complaints versus shipping questions
I tagged every email by type after I'd finished and looked at what Auto routing had chosen. Shipping questions—"Where's my order?"—went to Nova Micro 91% of the time. These emails needed a tracking number, an apology, and nothing else. Nova Micro is fast and costs almost nothing. Perfect fit.
Refund approvals under R500 went to Haiku about 60% of the time, Nova Micro the rest. I think Auto routing picked Haiku when the customer's email was long or emotional, Micro when it was a two-line "I want a refund." I didn't control that split—Auto routing decided—but it made sense. Haiku's better at tone-matching when someone's upset.
The angry complaints—eight emails, all caps, multiple exclamation marks, one person who called me a scammer—went to Claude Sonnet 4.5 every time. Sonnet wrote apologies that sounded human, asked clarifying questions without being defensive, and de-escalated two situations that could've turned into Takealot seller rating disasters. Sonnet costs more—about R0.40 per call—but it was worth it. I would've spent twenty minutes per email drafting those replies myself, and I probably would've sounded annoyed by email three.
Gemini Flash handled anything with an image attachment: photos of broken items, screenshots of tracking pages, one person who sent a picture of the wrong product with a handwritten note in the frame. Flash processed the image, understood the context, and drafted a reply. It picked Flash over Sonnet because the task was image-heavy but didn't need Sonnet's reasoning depth. Cost was somewhere in between—R0.15 to R0.25 per call.
I never saw DeepSeek or Llama get picked. I think Auto routing avoids them for customer service emails because they're better at technical or creative tasks than polite refund approvals. That's fine. I wasn't paying for models I didn't need.
The one thing Auto routing couldn't do
Auto routing drafted replies. It didn't send them. I still had to review every email, click send, and update the Takealot seller portal with the refund or return tracking number. That took another ninety minutes after the drafting was done. If Kryotta's Gmail connector could push replies directly—maybe with a confidence score, auto-send anything above 95%—I'd have saved the full four hours. As it was, I saved two and spent R118 instead of R300. Not perfect, but better than typing "We apologize for the inconvenience" seventy times while the inverter beeps in the background.
Questions people ask
Does Auto routing work if you don't know which model to pick?
Yes, that's the point. You write the prompt, Auto routing picks the model based on what the task needs. I didn't choose Haiku for refunds or Sonnet for complaints—it chose them. You can override it and force one model if you want, but I didn't need to.
What happens if you run out of power mid-batch?
Nothing breaks. Your drafts save in Kryotta, you reconnect when the power's back, and you keep going. The Gmail connector doesn't re-pull emails you've already processed. Just don't leave the sync running on mobile data unless you've got a big bundle.
Is R118 for 140 emails realistic or did you cherry-pick?
That's the real number: R28 in model calls, R90 in data overage. If I'd been on fiber the whole time, it would've been R28 total. A VA would've cost R300 minimum, assuming they could work during load-shedding and knew Takealot's return policies.
Can you use this for Shopify emails that aren't from Takealot?
Yes. The Gmail connector doesn't care where the email came from. I used it for Takealot returns because that's what was sitting in my inbox, but it works the same for direct Shopify customer emails, supplier queries, or anything else that hits Gmail.
If you're spending hours a day replying to the same eight customer questions, connect your Gmail to Kryotta and let Auto routing handle the first draft. You'll still review everything—you should—but you won't be rewriting "We've processed your refund" from scratch while the power clicks off in the background. Start with your inbox here.
