As always WordPress makes things very simple and a large number of accessible plugins can generally grimy the waters a little bit and make judgment difficult. Now, you do not need to be concerned at all because here some essential plugins has been described:
1. Contact Form 7
If you are in need of a contact form plugin, then this is ideal for you. You can arrange multiple forms with a range of form fields that will furnish any of your requirements; text areas, comment boxes, needed fields and radio buttons – Contact Form 7 plugin is the choice for you.
2. Fast Secure Contact Form or FSCF
This has been a good choice for a very long time due the fact that it is just straight forward to fix; it has not got as many highly developed features but it is still quite authoritative.
3. Gravity Forms
Whereas this is a premium plugin and not generously accessible from the WordPress plugin depository like Contact Form 7 and Fast Secure Contact Form you should not miss out this plugin as there is a cause why this is not a free plugin.
There is also an access to add-ons such as send data from Google sheet that you can incorporate into email list providers like Mail Chimp, and Aweber, etc. Overall, Gravity Forms is a very powerful plugin that should not be avoided.
So, I hope that this short list of authoritative plugins will be of some use to you.
