Ways of communication means of Communication-In Modern life

Social Media – Direct Message (DM) 
Social media doesn’t necessarily need to be completely public. Almost every social media channel offers a direct messaging option, some of those messaging services even have their own messaging app such as Facebook Messenger.
Private messaging through social networks has the same intimacy as email but tends to be less formal.
Businesses should only contact someone through Direct Message if the customer has reached out to them through that channel. However, certain direct messaging techniques are becoming a little more acceptable on some social networks such as Facebook. Facebook Messenger Bots are now seen as the norm and can help you to connect with your audience through Facebooks messaging service.
Instant Message (IM)
While some forms on Instant Message falls under social media like Facebook Messenger, there are a wide range of Instant Messaging platforms that aren’t connected to social networks such as Google Hangouts and WhatsApp.
IM is a great tool for quick informal chats or group chats.
SMS Text Messaging
We are all aware of the uses of text messaging. They are short, generally informal and are a good way to communicate small bits of information that can be received and replied to at the recipient’s own leisure.
These days we are almost always within arm’s reach of a mobile device, so it isn’t a surprise that more people are using their smartphones more than computers to search, research and communicate than ever before, making it the perfect platform to engage with your audience.
Email Marketing 

The first mass email was sent back in 1978 and even back then it was highly successful. However, today it is one of the most underestimated marketing platforms around, despite being one of the most beneficial in terms of return on investment.
Email marketing can be used for many different purposes, including to push products and services, spread news, raise brand awareness or to deliver a message to the masses.
Over the years, most businesses would have accumulated a great deal of email address and in many cases, they would go to waste. With email marketing those email addresses will enable you to reconnect with old clients as well as connect with new potential clients.
