It’s six hours to Black Friday. Your campaign’s locked, loaded, and you hit Send on that big WhatsApp blast.
Then… crickets

Half your messages are stuck. Customers aren’t seeing your offer. Your boss is asking for updates. And you’re stress-refreshing your dashboard, desperately hoping those delivery numbers will magically improve.
Sound familiar?
Here's what's probably happening:
Let’s dive into why this actually happens. Turns out it's not you, it's actually Meta's delivery limits, frequency capping, and a dozen other invisible guardrails that throttle bulk sends just when you need them the most. Here's the full list of what can go wrong behind the scenes.
Meta has implemented these restrictions to provide some relief to your customers, who are already overwhelmed by promotional messages from every brand under the sun. While this is great for the end-user experience, does it work for marketers trying to hit quarterly targets? Not so much.
What happens is that delivery and open rates take a plunge. And you're left here to pick up the pieces, manually resending all those messages that didn't go through at 2 AM.
Well, not anymore.
Smart Retries is your built-in safety net that automatically detects temporary delivery blocks, pauses, and rate-limits—then resends your campaigns.
When your campaign hits delivery roadblocks, ZEPIC intelligently waits for the best moment to try again. ZEPIC monitors which messages failed and automatically queues them for retry attempts according to your settings. You can configure the number of retry attempts (1-7 times, with 3 recommended) and the timing intervals (from 2 hours to 48 hours apart, with 24 hours recommended).
Smart Retries distinguishes between permanent failures (like blocked numbers or opt-outs) and temporary hiccups (like Meta's rate limiting). It won't waste your configured retry attempts on messages that are genuinely blocked, but it'll use them strategically for messages that just hit traffic jams.
Adaptive Pacing: Learns behavior patterns and spaces out retries so you stay compliant.
Delivery analytics: See every retry attempt, success, and (rare) permanent fail in one view.
This is perfect for those make-or-break moments that every D2C marketer knows, such as product drops where you need to keep hype alive, or for holiday surges, and back-in-stock alerts where you guarantee that your message reaches customers when the inventory is fresh, not when it's sold out again.
Here’s how to enable Smart Retries in your ZEPIC account:
Step 1: In your WhatsApp campaign setup screen, toggle the button "Smart Retries."

Step 2: You can set up to 7 retry attempts. Choose a gap of 2 hours to 48 hours between each retry. We recommend starting with three retries at a 24-hour interval and watching your metrics.
đź’ˇ Pro tip: For time-sensitive campaigns like 'sale ends today' offers, keep intervals under 24 hours to ensure messages reach customers while the offer is still valid.

Step 3: Continue with the rest of your campaign while ZEPIC works in the background to handle any delivery hiccups.
Smart Retries knows when to hold back because we care about your account reputation and don't want you to get blocked. It won’t waste time or your credits on messages that are never going to make it through. Like when a template gets rejected by Meta, when customers have opted out of communications, when phone numbers are invalid or disconnected, or when your WhatsApp Business account hits policy violations. Smart Retries focuses its efforts only on temporary delivery issues that have a real chance of success on retry.
