Throughout the day you will receive many emails, but it is possible that at some point you are waiting for a response from one in particular. The iPhone Mail application allows you to configure an option with which you will receive a notification when a specific email receives a response. This is how you should do it.
Before starting you should know that this option must be activated at the time of writing the mail, so it cannot be applied to mails that have already been sent.
To get started, open the Mail app on your iPhone and click on the button to compose an email located in the lower right margin (the one with the paper and pencil icon). Press “Subject” and you will see that an icon with a bell appears just to the right. Click on it and click “Notify Me”. Now you will see that the bell is blue, which means that the option is activated. To finish complete the mail and send it to its recipient.
When your mail is answered, the system will notify you with a notification regardless of whether you have disabled the application’s notifications.
In addition to this function, you also have another one to filter important emails. It is about making the emails of some contacts reach you to a specific mailbox called VIP. To do this, just click on the address of the contact in the Mail app and click “Add to VIP list”. You will be able to find the VIP mailbox along with the other mailboxes and in it you will only see the emails of the contacts you have selected.
