There are two types of campaigns a marketing team should be using. Don't confuse the two either. I often see marketing teams label everything as a 'campaign' without enough specificity to the scope of the campaign.
I use a simple model of micro campaigns and integrated campaigns
A micro campaign is a highly targeted campaign at a specific audience that are executed by marketing only. It lasts a day to maybe up to a month.
Examples include email sends, paid ad campaigns, and a partnership with an influencer.
You can still ask sales or customer success teams for opinions and feedback, but a micro campaign is something marketing can fully execute on their own.
A integrated campaign is a campaign that's much larger and involves marketing plus at least one other team. It spans at least a month, a quarter, if not longer, and requires multiple teams to to execute it. It's planned, executed, and analyzed my different teams and each have campaign specific goals.
A product launch is good example of integrated campaign. Or entering a new market or going after a new set of accounts.
Pick the right campaign wisely.
