WhatsApp is a one-stop solution for media and document sharing along with the fact that it’s now bringing more ways to use this Facebook-owned platform. The app started as just an instant messenger back in 2009 but has quickly grown into something much bigger than expected; seen by how popular they are among people worldwide who prefer contacting another person through WhatsApp these days.
In the digital age, effective communication is crucial for businesses and individuals alike. WhatsApp, with its vast user base and instant messaging capabilities, has become a preferred platform for disseminating information quickly. However, one common challenge users face is the need to save a contact’s number before sending a message. This article explores methods to send WhatsApp messages to unsaved numbers, commonly referred to as “WhatsApp blasting,” without the necessity of saving contacts.
WhatsApp messages are now the most popular form of communication, but there’s one major downside: you can’t send them without first saving your contact in the smartphone. However, somebody came up with an idea for how to use WhatsApp even if they don’t have access or saved data on their phone and it works quite easily too . Whether this technique will work well depends entirely upon individual devices as other apps may affect whether sending robust chats becomes possible at all.
However, it is extremely annoying that you need to save the mobile number in your contact list before you are able to send out messages to the person which you want to contact. Currently, there are 3 methods to send out your WhatsApp messages without saving the number in your phone book.
Understanding WhatsApp Messaging
WhatsApp is a widely used messaging application that allows users to send text messages, voice notes, images, videos, and documents. With over 2 billion users globally, it has become an essential tool for personal and business communication (Kamdjoug, 2023). The platform’s features, such as group chats and broadcast lists, enable users to communicate with multiple contacts simultaneously, making it a powerful tool for marketing and outreach (Marlinah, 2023).
The Importance of WhatsApp Blasting
WhatsApp blasting is particularly beneficial for businesses aiming to reach a large audience quickly. This method allows companies to send promotional messages, updates, or important information to potential customers without the need to save their numbers. The ability to communicate directly with customers enhances engagement and can significantly impact purchasing behavior (Kamdjoug, 2023). Studies have shown that effective communication via WhatsApp can lead to increased customer loyalty and impulse buying (Kamdjoug, 2023).
Methods to Send WhatsApp Messages Without Saving Contacts
Use API URL
Use API URL to send a WhatsApp message to the number you want to send to. This method is specifically designed for sending out 1 message at any given time. Here are some of the steps to take:
- To send a text message using WhatsApp’s API, open the web browser and paste “https://api.WhatsApp/send?phone=number”.
- To send a WhatsApp message to someone in another country, just replace “number” with their phone number with the country code.
- Omit any zeroes, brackets, or dashes when adding the phone number in international format.
- The number that you provided should have a WhatsApp account.
- Click on the “Message” button.
- You will be taken to the WhatsApp app with a chat being open for the said contact.
- Repeat Step 1 to 6 if you want to send out to different numbers.

Using WhatsApp Web or Desktop Application
One of the simplest methods to send messages to unsaved numbers is through WhatsApp Web or the desktop application. Users can initiate a chat with any number by entering a specific URL format in their web browser. You can create your own link with a pre-filled message which will automatically appear in the text field of a WhatsApp chat. This method also is designed to send out 1 message at any given time. Here are the steps:
- Use https://wa .me/whatsappphonenumber/?text=urlencodedtext
- Replace the whatsappphonenumber to the mobile number which you want to send to. You need to follow this format . For example, 6 (country code) 0126462522 (phone number)
- Replace urlencodedtext to the message you want to pre-filled for you. Here is the formula & example to setup pre-filled message.
- Example: https://wa.me/60125332288?text=I’m%20interested%20in%20your%20car%20for%20sale
- The pre-filled message is I’m interested in your car for sale. The use of %20 is for space bar.
- Repeat Step 1 to 3 if you want to send out to different numbers.
When this link is opened, it redirects the user to a chat window with the specified number on WhatsApp Web. This method does not require saving the number in the contact list and allows for immediate messaging (Rahmatulloh et al., 2023).
WhatsApp has introduced a new feature that allows you to send messages without adding the recipient’s number or email address to your phone. The good part about this is security, as there are no third-party apps needed and it will always be encrypted when sent through their servers.
However, if you have lots of number you want to send out in 1 go without having to repeat the steps of 1st Method and 2nd Method again and again, you can use 3rd Method.
Using Third-Party Applications: WhatsApp Blast
Several third-party applications and services facilitate WhatsApp messaging without saving contacts. These applications often provide bulk messaging features, allowing users to send messages to multiple unsaved numbers simultaneously. However, caution is advised when using such services, as they may violate WhatsApp’s terms of service, potentially leading to account suspension (Muzanima et al., 2024; Rafi’ulhaq & Handoko, 2024).
One of the third party application is WhatsApp Blast by Yaeris. This solution enables you to craft out your content and upload all the mobile numbers into a server. This server will send out your message and pre-filled all the messages for you to your targeted recipients. You can send out thousands of WhatsApp messages without having to save any number in your contact list. Here are the steps for 3rd Method:
- Go to WhatsApp Blast
- Purchase the amount of credits of messages you want to send out
- Login to the portal
- Draft out your content message
- Save all the phone numbers in Notepad or .txt format. Remember to insert country code in all of your numbers. You can mix all kinds of international numbers in 1 file.
- Upload the file which you have created in our server.
- Click on “Submit” to submit your campaign. Now your campaign is on queue and waiting to launch out its messages to all of your phone numbers which you have uploaded inside the .txt file. Yaeris’s service level assurance is 24 hours to complete your entire campaign.
When you finish your credits, you can topup again by buying at the website again. Hope this article helps you to understand what are the ways to send out WhatsApp messages without saving the number in your contact list.
Creating a Click-to-Chat Link
Another effective method is to create a “click-to-chat” link. This link can be shared via social media, email, or websites, allowing users to initiate a chat without saving the number. The format for creating a click-to-chat link is similar to the one used for WhatsApp Web:
https://wa.me/<countrycode><phonenumber>
For example, for a US number, the link would look like this:
https://wa.me/11234567890
When users click on this link, they will be directed to a chat with the specified number on their WhatsApp application, enabling them to send messages directly (Rahmatulloh et al., 2023; Diantoro et al., 2024).
Utilizing WhatsApp Business API
For businesses looking to implement WhatsApp blasting on a larger scale, the WhatsApp Business API offers a robust solution. This API allows companies to send messages to customers without saving their numbers. However, it requires technical integration and adherence to WhatsApp’s policies regarding messaging frequency and content (Suryono et al., 2019; Sayudin et al., 2024). The API is particularly useful for customer support and transactional messaging, providing businesses with the tools to engage effectively with their audience.
Best Practices for WhatsApp Blasting
While WhatsApp blasting can be an effective communication strategy, it is essential to follow best practices to ensure compliance with regulations and maintain customer trust:
- Obtain Consent: Before sending messages to unsaved numbers, businesses should seek consent from recipients. This not only complies with data protection regulations but also fosters trust and enhances engagement (Badrinathan & Chauchard, 2023; Nizah & Bakar, 2021).
- Provide Value: Ensure that the messages sent are relevant and valuable to the recipients. Whether it’s promotional offers, important updates, or useful information, the content should resonate with the audience (Heryandi, 2022).
- Limit Frequency: Avoid overwhelming recipients with excessive messages. Establish a reasonable frequency for sending messages to prevent recipients from perceiving the communication as spam (Omar et al., 2018; Fahrudin et al., 2020).
- Monitor Engagement: Track the performance of WhatsApp blasting campaigns by analyzing metrics such as open rates and response rates. This data can help refine future messaging strategies and improve engagement (Kurniawan & Sutabri, 2023; Suryono et al., 2023).
- Respect Privacy: Be transparent about how customer data will be used and ensure compliance with privacy regulations. This builds trust and encourages recipients to engage with your messages (Hidayah et al., 2021; Sutikno et al., 2016).
Conclusion
WhatsApp blasting offers a powerful method for businesses and individuals to communicate effectively without the need to save contacts. By utilizing methods such as WhatsApp Web, click-to-chat links, and the WhatsApp Business API, users can send messages to unsaved numbers efficiently. However, it is crucial to adhere to best practices, including obtaining consent and providing valuable content, to maintain customer trust and engagement. As digital communication continues to evolve, mastering tools like WhatsApp will be essential for successful outreach and marketing strategies.
