Marketers are fast becoming jacks of all trades and masters of all. The latest software platforms and improvements to online communications and automation means that a skilled marketing employee will now be able to wear many hats, from designer through to copywriter, and run whole campaigns single handedly.
We use and are skilled in 9 out of 10 of these platforms and use most on a daily basis so I can definitely vouch for them.
Where they thrive, or stand out from the crowd, is their ease of use and their ability to grow and adapt to a changing market.
If you are just starting out in marketing or are a seasoned vet I would recommend getting to know these as you will no doubt b using 1 or all at some point.
