WhatsApp vs Email vs SMS Broadcast

The advent of smartphones and the internet has seen customers move from Mails to SMSs and finally to WhatsApp. Customers could only communicate with one another over the phone for one hundred and sixteen years. And they eventually moved to SMSs as their favorite communication channel, given the ease and cost involved. The adaptability of communication technology has seen a shift over a period of time which has become more agile and dynamic over the past few years. 

Consumers today spend a lot of time on conversational channels, which has created new opportunities for businesses to get closer to their customers at every stage of the customer lifecycle, from marketing campaigns to pre-sales support to after-sales care. It's a win-win situation for both parties. Brands can save money on operations while improving customer engagement, and customers benefit from improved shopping experiences with less friction. 

Marketers, and businesses, are embracing these conversational channels as a new way to connect with customers and prospects. However, every company's quest to modernise its marketing eventually leads to the same question. Which of the three marketing channels, WhatsApp, SMS, and email, is the most effective?

Let's understand what each channel brings to your table and how it can help scale up the business and is required for successful marketing campaigns. 

What is Email Marketing?

Email marketing is a powerful marketing channel that uses email to promote your company's products or services. It is a type of direct marketing as well as digital marketing. Incorporating it into your marketing automation efforts can help make your customers aware of your latest items or offers. 

Through various types of marketing emails, it can also play a key role in your marketing strategy by generating leads, raising brand awareness, building relationships, and keeping customers engaged between purchases. People are as active as ever on email, despite countless headlines predicting its demise every year. However, audience cohorts have different preferences and behaviors. As a result, businesses must understand their customers' age demographics, as this has a direct impact on which channels they should prioritize. 

What are the benefits of Email Marketing and what makes it a smart solution for communicating with your audience?

1. Personalized and targeted content

Email is the ideal channel for driving engagement, from crafting the perfect subject line to images that resonate with your customers and valuable content that helps your audience. You can segment your customers into different lists based on their preferences and send highly personalized content with email marketing. Ignore the temptation to make a hard sell too soon in the process. Create a bond with your customer that can grow over time by first cultivating a strong foundation of trust between your brand and the recipient.

2. Drive sales and revenue

Email marketing is ideal for capitalizing on impulse purchases. There aren't many other marketing platforms that allow customers to go from seeing an offer to buying something with just two clicks. Email newsletters can drive sales like no other channel, with a compelling call to action and a link straight to the checkout. You'll find a wealth of information on how to use psychology in email marketing to improve your results, including one of our most popular articles. The psychology behind successful email marketing.

3. Low cost

One of the most obvious benefits of email marketing is that it is less expensive than traditional marketing channels. There are no costs for printing or postage, and no fees are paid in exchange for exposure on a specific billboard, magazine, or television channel. To automate, track, and evaluate their emails, email marketers should consider investing in specialist software. 

Although there may be a small cost associated with sending thousands of emails at once, these costs are significantly lower than those associated with other marketing channels. 

4. Metrics to learn what works

When it comes to customers opening your emails, you only have a short window of opportunity. A high open rate indicates that your customers are familiar enough with your brand to want to hear from you at any time of day. Following that is your click-through rate (CTR), which gives you an idea of how many customers took the time to read your email and click on the links within. The goal after a customer has clicked through your email is to get them to convert. Your email conversion rates are an important metric to track because they indicate how well your email's call-to-action performed. Constantly trying and testing the content and call-to-action buttons can give you a better understanding of what works for higher conversions and what does not. 

5. Email Broadcasting

Email broadcasts, unlike SMS broadcasts, can be configured so that recipients can know who else has received the same message. Email broadcasts make it simple to send targeted and personalized messages. You have a lot of design freedom because you can include images, gifs, and even videos. It generates a $36 ROI (Return on Investment). But before you will start email broadcasting, remember to improve your email deliverability and also verify disposable emails.


What is SMS Marketing?

Despite the advancements in mobile phones, SMS has been and continues to be at the forefront of mobile marketing. SMS marketing, also known as Short Message Service (SMS) marketing, uses text messages to send promotional offers to customers. 

The majority of businesses still use SMS marketing to sell products and raise brand awareness. Bulk SMS blasting is still an effective way to promote new offers and discounts. Some businesses also use an SMS gateway to make the campaigns easier and more secure.Custom SMS marketing, on the other hand, is particularly effective for personalized users such as tracking orders, OTPs, and account verification. SMS has a huge global reach, which is one of its biggest advantages. When you add in the ability to send messages without using the internet, you have a channel that allows you to connect with customers in places where mobile data isn't always available or free. 

What are the advantages of SMS marketing?

1. Reliability 

SMS has a higher open rate as compared to Emails, 98% of SMS messages are read within 5 minutes of being sent. In most cases, customers will respond in as little as 90 seconds!  Email, on the other hand, has a 90-minute average response time and a 22% average open rate. SMSs can reach out to people bypassing the email spam filter black hole. So instead of spending a ton of time and money carefully crafting emails just to end up in the spam folder, start using text messaging. You will enjoy a direct line of communication between you and your customers.

2. Mobile-friendly

It's critical these days to present your company as mobile-friendly. People are increasingly using their mobile devices for tasks such as shopping and browsing. You don't want to miss out on such an opportunity. SMS marketing is an important part of making your company mobile-friendly, and it can be a valuable addition to your mobile marketing strategy. Moreover, SMS does need internet where modes of communication are dependent on the Internet or WiFi. 

3. Easy opt-outs

Your customer can't do much to break free from this never-ending cycle, but they can unsubscribe from your marketing texts.  Most SMS marketing tools, like email marketing, make it simple for users to opt out. This, believe it or not, is one of the most important advantages of text marketing. A customer who receives a barrage of texts from your company may become irritated and decide not to buy from you. Accept the opt-out in this case and, after some time has passed, try appealing to these customers through other channels.

4. Flexible and customizable

One of the most advantageous aspects of SMS marketing is its versatility. You can mix and combine SMS messages to market your brand in a variety of ways. You can use SMS to announce a sale, offer a limited-time discount, reward loyal customers, advertise a new product, share information, and more. It's an excellent tool for any business, large or small.

5. SMS Broadcasting

Any mobile device, including non-smartphones, may send and receive SMS broadcast messages. This helps you reach out to clients who don't have access to a smartphone. The recipients have no way of knowing if the communication was sent in bulk. SMS broadcast messages do not require data or WiFi and can be sent even if the internet is unavailable.

What is WhatsApp Marketing?

In comparison to SMS marketing, WhatsApp marketing is a relatively new kind of marketing. WhatsApp has revolutionized and offered users sophisticated communication possibilities since its inception. Although there are many popular messaging apps, WhatsApp is the most appealing and user-friendly. People use WhatsApp because it is the primary way of communication and texting for 78% of users, and it is also the primary means of conducting business. WhatsApp allows you to share files and documents in ways that SMS can't. WhatsApp creates a branded relationship with users and provides a slew of marketing opportunities. WhatsApp generates three times the amount of traffic that SMS does, making it far more suitable for marketing. You can quickly message your consumers and react to their questions using either of them. You can use your WhatsApp Business account to manually react to client questions. You can also send messages to your customers.
