Hi,
I wanted to take a moment to introduce myself.

I am Harper, Working for Keka(HR & Payroll Software). Keka’s cloud-based HRMS software, built to help businesses manage their talent better and grow faster.
I am trying to get in touch with you to open up a discussion around an opportunity and collaborate to add more value to your readers.

I had a few ideas for insight-driven articles that I think your readers would love to and all this can be backed by my knowledge and expertise. 

The topic ideas that I had are:

Idea 1: Ten Tips For A Successful Performance Appraisal
Idea 2: Everything You Need To Know About Payroll Processing
Idea 3: What Are The Main Objectives Of Human Resource Management?

This could be a great opportunity for your readers to read a fresh perspective on these topics from someone with years of experience. 
You can see some examples of our other published articles mentioned as below:

Published Article 1: https://snacknation.com/blog/virtual-team-building/ 

Published Article 2: https://whatfix.com/blog/employee-training-plan-templates/

Also I will be happy to discuss more other ideas that you have, even if that is giving expert comments for pieces of content you are already working on.

I look forward to hearing back from you
