You already have some answers thanks to your persona. But if you decide to manage your communication alone, there is one essential point for me: to please yourself ! Communication requires time and energy. To see results, you can't just publish once in a while. You have to be consistent in your content . So if you choose a communication channel that tires you out, we know what will happen. You will give up in a few months.
For me, the best communication channels for your business are therefore those that combine the presence of your target and pleasure for you . Without this, it will be complicated to see results in the long term.
Of course, if you choose to entrust the writing of your content korea whatsapp number data to an external person (like me for example), the communication channels will be essentially based on the presence of your target and their relevance for your business.
What are your means?
Last question but just as important as the previous ones: the means that you can dedicate to your communication, whether financial or human .
This last step is linked to your business and your desires. But before starting your communication, it is essential to take this into consideration. Do you have a member of your team who can manage this part? Do you have a budget to grant him for advertising or printing flyers/posters etc?
If you are alone, do you think about delegating your communication actions to a service provider? In this case, you will have to define a budget but also a little time to find the best person to accompany you.

If you prefer to manage your communication alone, how much time can you dedicate to it each week? This will help you define the actions you can put in place . Don't try to do too much if you have little time for your communication. You will never be able to publish 5 posts on Instagram and Facebook and write 2 blog articles per week if you only have 2 hours/week to manage your communication.
By being aware of your means, you will be able to prioritize your actions based on this (and your objectives of course). This will help you to be more efficient and make the right choices when it comes to thinking about your communication plan.
