Create,Open and Send an Email

There are number of website where we can create an Email account, but some of are the popular websites Google, Hotmail, Rediffmail, Yahoo etc. Here we will describe you only about the Google's Gmail account.we’re going to show you how to get started with email by creating an account in Gmail.

You’ll need:

A computer with internet access and a web browser installed on your computer

Follow these step-by-step instructions to create a Gmail account

 

Step 1: Go to Google

 

Open up your internet browser and go to the Google home page: http://www.google.com and then click on Gmail at the top right corner of the page

Step 2: Create an account

 

You’ll now be in the ‘Sign in’ section. As you don’t have a Google account yet, you need to create one. Click Create an account.

Step 3: Set-up

 

To set up your new account, Google needs some information about you – first, your first and last names. The ‘choose your username’ is the unique email address that you wish to use, which will be placed before ‘@gmail.com’. Because it needs to be unique, Google may have to check the availability of any name that you decide on to make sure that no one already has it. Type an email name into the ‘choose your username’ box and then fill out the rest of your information.

If the email name that you requested in is not available, you’ll get a message saying that somebody already has that username and offering you some alternatives. You can decide to accept one of the alternatives or type in another name and check its availability once more. You will have to complete some of the other boxes again. You may have to do this a few times. Once you finalise your email address, it’s a good idea to make a note of it so that you can refer to it until you remember it.

 

You’ll need to come up with a password so that you can log in securely to your account. Google may explain that you should try one with at least 8 characters long to be secure. Use letters and numbers to make the password more secure and difficult to guess. You can add an existing email address to keep your new email secure as well.

Step 4: verification

 

To get to the next steps you will need to Accept Google's privacy and terms first, once you have read it click on I Agree.

Google will now ask you to verify your account via text or voice call, select the option that you want and click on Continue.

If you chose the text message option you will see a new window where you will have to enter the code that Google has sent to your mobile number. Select Continue and congratulations you have created your Gmail account.

Step 5: Google mail dashboard

 

You will be automatically redirected to Gmail's dashboard and once you have read all of the information your Gmail is now ready to use. On the left hand side you will be able to see your inbox, sent mail and trash, you will also be able to compose emails from this list too.

How to send an email

You’ll need:

 

• a computer with active internet connection
• an email account set up and ready to send and receive emails.

Follow these step-by-step instructions to send an email

 

Step 1: Log in to your Gmail account so that you are on the dashboard (main page) of your mail account.

 

Step 2: Click Compose.

Step 3: A new blank email window will open up. In the ‘To’ box, type in the email address of the recipient.

Step 4: You might want to include someone else in your email to ‘keep them in the loop’. You can do this by clicking Cc or Bcc, which will open another field. ‘Cc’ means ‘carbon copy’ and ‘Bcc’ means ‘blind carbon copy’. Adding an email address to the ‘Cc’ field means that that person will receive a copy of the email and all the other recipients will see their email address. If an email address is put into the 'Bcc’ field, the person will get a copy of the email but no other recipient will see that address.

 

If you are sending the same email to lots of different people, it’s a good idea to put all the email addresses in the ‘Bcc’ field to keep your ‘mailing list’ confidential. That way, there’s no chance that it could fall into the hands of a spammer or hacker.

Step 5: The subject field allows you to give the recipient an idea of the topic of your email, like a heading. You don’t have to put anything in the subject box, but it can help when viewing and sorting email.

 

Step 6: Email text can be formatted in a similar way to text in a word document. You can change the font style, colour and size using the formatting icons. You can also create bullet points and check the spelling of your email. Choose your formatting from the menu shown.

Step 7: Type your message in the main body field of your email.

Step 8: When you’re happy with your email, click the blue Send button at the bottom of the compose window.

Step 9: The email you’ve sent will now be stored in the ‘Sent Mail’ folder on your Gmail dashboard. You may have to run your mouse pointer over the Inbox folder link to see the other folders.
