Why can't I create a Contact List of more than 16 people

[lilly76]

I have to send out an email to about 20 people but cannot create a Contact List for more than 16.  I do type the list, but when it is checked there are some missing and it is very annoying as I have to go through the email in the heading and tick of the names that are there and add the missing ones.

It is very annoying.

Help needed please.

Create 2 lists, or use a mail client (app) such as the free Thunderbird

Thank you for your response.

I didn't think of creating two lists.  I am on a PC so it would be easier.

Am I right in assuming that Apps are only for the Mobile Phone and not the PC?

Much obliged.

I put app as folks understand that rather than mail client.

Thunderbird is a PC client.

Thank you.  I will download it and see how I get on.

Also, tonight I created a second list which showed saved successfully, but the email addresses weren't added to it.  Anyhow, I will try the App.

I have downloaded the App but how do I use it? Are there videos on line on how to use it?
