### Bulk Text Campaign FAQ's
This article covers how bulk text campaigns work in Walla, including batch times, DND hours, delivery expectations, and best practices for sending large or holiday-focused SMS campaigns. Use this guide to plan timely, effective messages for your clients
Updated over 5 months ago Table of contents
### For Studio Owners Using Walla
### 1. **When do automations send, once created? Can I choose the time the campaign sends?**
**Answer:** Our system batches and sends every 2 hours (up to DND hours). That means if you finalize/create your automation at 5:54 PM in your local time zone, it will run at the 6:00 PM batch window.
You cannot pick an exact minute (e.g., 5:37 PM), but you can choose to complete it before the next 2-hour window so the send happens soon.
If you wind up creating it just after a window has started, you’ll wait up to the next 2-hour slot.
### 2. **What are DND hours and how are they applied?**
**Answer:** DND = “Do Not Disturb” hours. These are blackout windows during which no bulk text messages will be sent to recipients. For Walla, the DND hours run from **7:00 PM to 8:00 AM** in the studio’s local time zone.
That means no messages will go out during that time period, even if your batch window opens. If a campaign is ready at 6:15 PM, it would not send at 7 due to DND it will be held until after 8:00 AM.
***DND opens at 8am, so we send at 8am/10am/12pm/2pm/4pm/6pm in your local time zone.***
### 3. **I have a rather large audience — will there be any delays in sending these campaigns?**
**Answer:** Potentially — when the audience list is very large, you may experience longer upstream queueing and potential delays in actually delivering to all contacts. To avoid risk:
- For large lists, we **recommend** creating the campaign **well before** the final batch window prior to DND begins. That gives the provider time to process all the SMS messages ahead of the blackout period.
- As a best-practice tip: If you have a large audience, consider **narrowing the list** slightly — e.g., segmenting by most engaged customers, recent visits, or specific offers — rather than doing one giant blanket send.
Studies show that **personalized or segmented SMS campaigns perform better** than broad blast campaigns. [Bloomreach+2Voxie+2](https://www.bloomreach.com/en/blog/bulk-sms-campaigns?utm_source=chatgpt.com)
- For example: one article notes that “bulk SMS … doesn’t necessarily have mass appeal” and suggests that targeted campaigns generate higher engagement. [Attentive+1](https://www.attentive.com/blog/bulk-sms-marketing?utm_source=chatgpt.com)
- Another piece states: “personalized SMS campaigns can significantly boost revenue and efficiency” when compared with generic mass texts. [Voxie](https://www.voxie.com/blog/personalized-sms-marketing-mass-text-messages/?utm_source=chatgpt.com)
So for Holiday season volume, better to send a well-timed, curated list than to risk a delayed or less efficient giant send.

### 4. **Can I pick a specific send time (e.g., at 9:05 AM or at 12:30 PM) for a campaign?**
**Answer:** Not exactly. Because we use 2-hour batching windows, you can aim to be ready just before a window (e.g., 9:59 AM) so your campaign goes at the 10:00 AM batch. But you cannot set an arbitrary minute. Plan to align with those windows. Also remember the DND window (7 PM-8 AM) when planning.
### 5. **What happens if someone’s number is on a DND / Do Not Disturb registry or has opted-out?**
**Answer:** We honour all opt-outs and any regulatory restrictions. If a recipient has unsubscribed from marketing texts, or if their number falls under a legally enforced DND registry (per regional telecom rules), our system will exclude that contact from the send. Make sure your subscriber list is clean and up-to-date ahead of Holiday campaigns to avoid wasted cost or messaging to invalid numbers.
### 6. **Are there best-practices for Holiday (e.g., Black Friday / Cyber Monday) bulk texts I should follow?**
**Answer:** Yes — especially given the higher volume and competitive inbox that comes with the holidays:
- **Segment your audience:** target most engaged, recent visitors, high-LTV customers, or by offer interest rather than sending to your entire list. (As noted above, targeted tends to outperform true mass blasts.)
- **Ensure message relevance & brevity:** The top SMS marketing guides emphasise high open-rates (SMS can have open rates nearing 98 %) and fast engagement. [Textdrip+1](https://textdrip.com/blog/sms-marketing-statistics?utm_source=chatgpt.com)
- **Pre-plan time-windows:** Know your batching windows and DND hours so you’re not caught sending too late or where messages get queued.
- **Use urgency correctly:** “Ends midnight”, “first 50 customers”, “while supplies last” — Holiday campaigns often perform better with clear time-bound calls-to-action.
- **Avoid over-messaging:** Because people are receiving more messages in this period, too many texts may lead to opt-outs.
- **Clean your list:** Remove inactive or unsubscribed numbers so you focus on engaged contacts.
- **Track & measure:** After your campaign, review delivery rates, click/open rates (where trackable), and conversions to optimize for future waves (e.g., follow-ups, last-minute flash offers).

### 7. **What does “batching every 2 hours” really mean for my send schedule?**
**Answer:** Simply: The system processes campaigns at fixed windows every two hours (e.g., 8:00 AM, 10:00 AM, 12:00 PM, 2:00 PM, … up to the last one before 7:00 PM if in DND zone). So if you submit your automation (and everything is configured and approved) at 2:45 PM, it'll go at the 4:00 PM batch window. If it's submitted at 4:05 PM, it'll go at the 6:00 PM window (provided that’s still before the 7:00 PM DND start). If it’s after 7:00 PM, it will go at or after 8:00 AM the next day. So timing your setup matters.
### 8. **How large is “large” for audience size, i.e., when should I expect possible delays?**
**Answer:** While “large” depends on many factors (carrier capacity, geographic spread, your list cleanliness, etc.), as a rule of thumb: if you’re sending to the majority of your list or sending thousands of messages, you should assume possible delays and buffer accordingly. If you’re unsure, run a test segment ahead of your main send to check delivery timing.
### 9. **If I narrow my list (segment) ahead of the send, what kind of segments are effective for studios?**
**Answer:** For studio-owners, some smart segments might include:
- Recent visitors (last 30 / 60 days)
- High-value customers (those who have spent above a threshold)
- Lapsed clients (haven’t booked in last 90 days)
- Offer-interested customers (those who've clicked via previous texts or emails)
- Localised offers (members within a specific ZIP code or neighbourhood)
The idea: use the audience data you already have to refine who you message so you drive higher conversion rather than high volume for volume’s sake.

### 10. **What if I submit a campaign and we hit a technical issue (e.g., message fail or delay)?**
**Answer:** If you suspect there is an issue (e.g., unusually low delivery rate, bounce rate, or recipient complaints), contact Walla support immediately — provide the campaign details, audience size, and send window. We’ll help troubleshoot with our team. For Holiday sends especially, plan a buffer window ahead of peak deadline so you have time to troubleshoot.
### Summary & Best Tip
When planning your Holiday bulk-text campaign in Walla: **plan early**, **segment smart**, **time with awareness of batching and DND**, and **prioritise relevance over sheer volume**. Doing so increases your chance of reaching the right people, at the right time, with the right message.
