Prepare Contacts for Bulk WhatsApp Messages
Getting your contacts ready is the first step before you send bulk WhatsApp messages. You have a few easy ways to import your contacts. Let’s look at each method so you can pick the one that fits your needs.
Google Sheets Import
Do you use Google Sheets to manage your contacts? You can connect your sheet directly to WASender. This method is quick and keeps your data up to date. You just copy the Google Sheet URL and paste it into SheetWA. The tool pulls your contact list and gets it ready for messaging.
Here’s a simple table showing the best way to set up your sheet:
Column Name | Description |
|---|---|
Recipient Name | The name of the contact |
Phone Number | |
Message Content | Optional text message to send (if needed) |
Make sure your phone numbers use the E164 format. That means you add the country code at the start. For example, a US number should look like +12345678900. This format helps WASender deliver your messages without errors.
Tip: Double-check your sheet before you start. Clean data means fewer mistakes and faster sending.
Excel and CSV Upload
If you keep your contacts in Excel or CSV files, you can upload them straight into SheetWA. This method works well if you already have a list saved on your computer. You just choose your file, select the right sheet, and map the columns.

Here’s another table to help you organize your file:
Column Name | Description |
|---|---|
Phone Number | Must be in E164 format with country prefix |
Text Message | The message to send to the target phone number |
You can send different messages to each contact if you want. Just add a column for custom messages. Remember to use the correct phone number format so your whatsapp messages reach the right people.
Note: You don’t need to convert your Excel file to another format. SheetWA accepts both .xlsx and .csv files.
Copy-Paste Numbers
Sometimes you just need to send a quick message to a small group. You don’t have a file ready. That’s okay! With SheetWA, you can copy and paste numbers right into the tool. Paste your list, set the country code, and write your message.
This method is perfect for last-minute updates or small campaigns. You don’t need to worry about formatting a spreadsheet. Just make sure each number is correct and includes the country code if needed.
Quick Tip: Use this feature for urgent messages or when you have only a few contacts.
Getting your contacts ready is easy with WASender. You can use Google Sheets, Excel, CSV, or just paste numbers. Each method helps you send bulk whatsapp messages faster and with fewer mistakes.
Country Code Settings
Getting country codes right is a big deal when you send bulk WhatsApp messages. If you skip this step or make a mistake, your messages might not reach anyone. You want every message to land in the right inbox, so let’s make sure you set up your country codes the right way.
When you use SheetWA, you get three easy options for handling country codes:
Numbers without country code: Your list has only local numbers. You pick a default country code, and SheetWA adds it to every number.
Numbers with country code: Your numbers already include the country code. SheetWA uses them as they are.
Country code from a separate column: Your file has one column for the country code and another for the phone number. SheetWA combines them for you.
Tip: Always double-check which format your contact list uses before you start. This saves you from sending messages to the wrong people.
You want your numbers to be clean and ready for WhatsApp. Here are some best practices to follow:
Best Practice | Description |
|---|---|
Format Numbers Correctly | Make sure phone numbers use only numbers—no spaces, dashes, or symbols. |
Include Country Codes | Always add the correct country code, right at the start of the number. |
Double-Check Formatting | Look over your list to catch any mistakes before you send your messages. |
If you have a list of numbers without country codes, just set your default country code in SheetWA. For example, if you’re messaging people in the US, set the country code to “1.” SheetWA will add it to every number. If your numbers already have the country code, you don’t need to do anything extra.
Sometimes, you might have contacts from different countries. In that case, use the “country code from column” option. This way, each number gets the right code, and your messages reach people all over the world.
Note: If you get the country code wrong, your message won’t go through. Take a minute to check your settings before you hit send.
Setting up country codes in SheetWA is quick, but it makes a huge difference. You’ll avoid delivery errors and make sure every message gets to the right person. Take your time with this step, and you’ll see better results every time you send bulk WhatsApp messages.
Create and Personalize Message Templates
Message Templates
You want your messages to look professional and save time. That’s where message templates come in. With WASender, you can set up templates for different types of messages. Maybe you send order updates, appointment reminders, or welcome notes. Templates help you keep your messages clear and consistent.

WASender uses a system to track the quality of your templates. This helps you know if your messages are working well or if you need to make changes. Here’s a quick look at the different template statuses:
If your template gets a low quality rating, it might get paused or disabled. This means you can’t send it until you improve it. The system checks how people react to your messages. If people like them, your template stays active. If not, you may need to update your message.
Tip: Keep your templates fresh and engaging. This helps you avoid delivery problems and keeps your audience happy.
Personalization Fields
People love messages that feel personal. When you add a name or special detail, your message stands out. WASender lets you use personalization fields like {Name} or {OrderID}. You can pull these details from your contact list or spreadsheet.
Here’s why personalization matters:
People feel valued when you use their name.
Generic messages get ignored.
Let’s say you want to send a message to your customers. Instead of “Hello,” you can say, “Hello, Sarah!” This small change makes a big difference. You can even add order numbers or appointment times. Your contacts will notice the effort.
If you want to create broadcast list messages that get results, always add a personal touch. This works for both regular chats and whatsapp broadcast lists.
Attach Media
Sometimes, words aren’t enough. You might want to send a picture, a video, or a document. WASender makes it easy to attach media to your whatsapp messages. You can share product photos, flyers, invoices, or even short videos.
Here’s a table showing what you can attach and the size limits:
Media Type | Supported Formats | Size Limit |
|---|---|---|
Images | JPG, JPEG, PNG, WEBP | 5 MB |
Audio | OGG, AMR, 3GP, AAC, MPEG | N/A |
Documents | PDF, DOC, DOCX, PPTX, XLSX | N/A |
Video | MP4 (H.264, AAC) | N/A |
Overall Message | N/A | 16 MB |
You just click “Attach Media,” pick your file, and add it to your message. Make sure your file is the right size. If you try to send a file that’s too big, it won’t go through. For most images, 5 MB is plenty. For all your message content, keep it under 16 MB.
Note: Adding images or videos can make your message more interesting. People are more likely to read and remember your whatsapp messages when you include media.
Message Formatting
You want your WhatsApp messages to stand out, right? Good formatting can help you do just that. With WASender, you can make your messages look more interesting and easier to read. You do not need to be a tech expert to add style to your words. Let’s see how you can use formatting to make your messages pop.

How to Send Bulk WhatsApp Messages
Batch Sending
When you want to send bulk WhatsApp messages with WASender, you do not have to send each message one by one. You can send messages in batches. This means you pick a group of contacts and send your message to all of them at once. Batch sending saves you time and helps you reach more people quickly.

If you have a big list, you can split it into smaller groups. This helps your messages get delivered faster and keeps your WhatsApp account safe. You just select the rows or contacts you want to include in each batch. Then, you start sending. It is that simple.
Tip: Sending in batches helps you manage large campaigns without feeling overwhelmed.
Time Gap Settings
You want your messages to reach everyone, but you also want to keep your WhatsApp account safe. That is where time gap settings come in. When you send bulk WhatsApp messages with WASender, you can set a time gap between each message. This makes your sending look more natural.

Here are some recommended time gap settings to help you avoid problems:
Sending interval: Adjust the sending interval to 180-190 seconds or 300-310 seconds to minimize the risk of account bans.
If you send messages too fast, WhatsApp might think you are spamming. By adding a small delay, you make your messages look like they are coming from a real person. You can change the time gap in the settings before you send bulk messages. This small step can make a big difference.
Note: A longer time gap is safer, especially if you are sending to a new list or a large group.
Message Preview
Before you send out your messages, you want to make sure everything looks right. WASender gives you a message preview feature. This lets you see exactly what your message will look like for each contact.

The preview feature enables you to verify your message content for accuracy before sending it out in bulk.
You can check the names, numbers, and any special details you added. If you spot a mistake, you can fix it before anyone sees it. This helps you avoid sending the wrong message or missing important information.
Always use the preview. It is your last chance to catch errors and make sure your bulk WhatsApp messages look perfect.
Delivery Report
After you send your bulk WhatsApp messages, you want to know what happened next. Did your messages reach everyone? Did some numbers fail? That’s where the Delivery Report in SheetWA comes in. This feature gives you a clear summary of your campaign. You see which messages went out, which ones got stuck, and why.
When you finish sending, just click the “View Report” button on your SheetWA dashboard. You get a list of all your recipients, their phone numbers, the message content, and the status for each one. You don’t have to guess or check each chat manually. The report shows you everything in one place.
Here’s what you’ll find in your delivery report:
Field | What It Tells You |
|---|---|
Phone Number | The number you tried to message |
Message Content | The exact message sent |
Status | Sent, Pending, Failed, or Not on WhatsApp |
You can use filters to sort the report. Want to see only failed messages? Click the filter. Need to check which numbers are not on WhatsApp? Use another filter. This makes it easy to spot problems fast.
Tip: Always review your delivery report after each campaign. You catch mistakes early and avoid sending to wrong numbers next time.
Sometimes, you see errors like “Number Missing” or “Not on WhatsApp.” If you spot these, check your contact list. Maybe you forgot a digit or used the wrong country code. SheetWA helps you fix these issues. Update your data, and resend the message. You save time and avoid frustration.
Here’s a quick checklist for using the delivery report:
Check for failed messages
Look for missing or incorrect numbers
Fix country code problems
Update your contact list
Resend messages if needed
The delivery report also helps you keep your data clean. If you see lots of errors, maybe it’s time to clean up your spreadsheet. Good data means better results.
You can use the report to track your campaign’s success. Did most messages go through? Great! If not, you know what to fix. This feedback loop helps you improve every time you send bulk WhatsApp messages.
Note: The delivery report is your best friend for bulk messaging. It keeps you informed, helps you correct mistakes, and makes your campaigns more effective.
So, next time you send out a batch, don’t skip the delivery report. You’ll work smarter and get better results with every campaign.
Best Practices for Bulk WhatsApp Sender
Avoiding Bans
Nobody wants their WhatsApp account banned, especially when you work hard to build your contact list. You can keep your account safe by following a few smart steps. Here’s what you should do:
Always get permission before you send bulk messages. If people expect your messages, they won’t report you as spam.
Limit the number of messages you send at once. Sending too many can look suspicious.
Give people a way to stop messages if they want. This lowers complaints and keeps your reputation strong.
Make sure your messages matter to your audience. If you send only useful or interesting updates, people will stay happy.
Watch your message quality. If you see more complaints or fewer replies, change your approach.
Use group chats for real conversations, not for spamming.
Never send messages too quickly. Add a time gap between each one to look more natural.
Tip: If you treat your contacts with respect, you’ll avoid most problems with bulk messaging.
Compliance Tips
You need to follow some important rules when you send bulk WhatsApp messages. These rules protect both you and your contacts. Here’s a table to help you remember the main points:

Consent and Opt-Out
Getting consent is not just a rule—it’s a way to show respect. When you ask people if they want to get your messages, you build trust. Here’s how you can do it:
Ask users to sign up through a form or in-app prompt.
Tell them what kind of messages they will get and how often.
Always give an easy way to unsubscribe. For example, add a line like, “Reply STOP to opt out.”
Note: When you let people choose, they feel valued. This leads to better engagement and fewer complaints.
If you want your bulk whatsapp messages to work, focus on consent and clear opt-out options. This keeps your audience happy and your bulk messaging safe. Following these best practices helps you use whatsapp business api tools the right way and keeps your account running smoothly.
Responsible Messaging
Responsible messaging is more than just sending out a bunch of WhatsApp texts. You want your messages to feel welcome, not annoying. When you send bulk messages, you shape how people see your brand. If you do it right, you build trust and keep your contacts happy.
Start by thinking about your audience. Would you want to get this message? If not, change it. Always get clear consent before you send anything. People like to know what they are signing up for. When you ask for permission, you show respect. This simple step can make a big difference in how people respond.
You also want to make sure your messages matter. Don’t send random updates or sales pitches that don’t fit your audience. Instead, share news, offers, or tips that help your contacts. If your message is useful, people will look forward to hearing from you.
Here’s a handy table to help you remember the main guidelines for responsible messaging:
Guideline | Description |
|---|---|
Obtain clear consent | Always ask for permission before sending messages. |
Use relevant and valuable content | Make sure your messages are helpful and interesting to your audience. |
Follow best practices | Stick to WhatsApp’s rules and bulk messaging tips. |
Monitor message delivery | Check if your messages go through and fix any problems quickly. |
Plan ahead | Give yourself time to prepare and get templates ready. |
You should also keep an eye on your delivery reports. If you see a lot of failed messages, check your contact list. Maybe some numbers are wrong or not on WhatsApp. Fixing these issues helps you avoid wasting time and keeps your campaigns running smoothly.
Planning ahead is another smart move. Don’t rush your campaigns. Give yourself time to create good templates and review your contact list. If you need approval for a message, start early. This way, you avoid last-minute stress and mistakes.
Remember: Responsible messaging is about respect. When you respect your contacts, they respect your messages.
Here are a few quick tips to keep your messaging on track:
Double-check your message before sending.
Keep your language friendly and clear.
Avoid sending too many messages in a short time.
Give people a way to opt out if they want.
Responsible messaging helps you build strong relationships. When you follow these steps, your contacts will see you as helpful, not pushy. That’s how you turn a simple message into a lasting connection.
Limitations and Considerations
WASender gives you lots of options for sending messages. But there are some things you should think about before you start. These points can change how you plan and send your messages.
No Scheduling
Sometimes you want to send messages at a certain time. Maybe you have a sale or an event coming up. WASender does not let you schedule messages. You must send them yourself when you want them to go out. This can make things harder for your business:
Tip: Set reminders so you do not forget to send important messages.
Manual Consent Management
It is very important to get permission from your contacts. WASender does not keep track of consent for you. You must manage who said yes and who wants to stop getting messages. This takes extra time and work, but it helps you follow whatsapp business api rules.
If you keep your records neat, you will not send messages to people who do not want them. This helps you build trust and keeps your whatsapp business api account safe.
No Chatbot or Automated Tracking
WASender helps you send messages, but it does not have chatbot features or automatic tracking. You must answer replies and follow up by yourself. Here is what this means for your messages:
You get more control over your chats, but you spend more time managing them. If you want to keep track of every reply or send automatic answers, you must do it yourself.
Note: WASender is best for small groups or casual chats. If you need more automation, you may need another tool.
Now you know what to think about before using WASender for your whatsapp campaigns. With good planning and organization, you can still get great results and keep your contacts happy.
