I'm a marketing director for an environmental firm. The golf and lunches disguised as networking or 'lunch and learns' are available to me, but I can't stand them so I tend to steer clear.
My day to day varies. Generally it kicks off with reviewing metrics reports -- how effective is my team's work in a daily, weekly, monthly, and yearly context? I also review the reports from other teams to identify where support is needed, directing attention to places where revenue is weaker. What that support looks like will vary by product and region; we might generate a local marketing campaign, or we might adjust the flow of targeting for a larger, national campaign. That will involve most of my team working on creative, which I then have to approve and sometimes deploy, depending on if it uses one of the channels I prefer to manage end-to-end (because sometimes it's just easier if I do it.)
Then it's working on the local and national campaigns that we run regularly. That can be either working on upcoming campaigns, swapping out creative for existing campaigns, or a mix of both. At this point my team and I have all worked together for several years so I can just say 'let's get x campaign together' and everyone will know what to do; if there's someone new, there's more hand-holding involved. A campaign will involve multiple pieces -- printed (trade magazines or direct mail), emailed, online ads, working with local and national professional associations.
The rest of the time will be spent working on other projects -- planning for events marketing and trade shows to make sure the sales reps have everything they need, writing reports, working on my budget to reconcile spending or planning for the next year, meeting with vendors (paper company, printing company, external design firm, data warehouse, very persistent media partner sales reps, etc.)
If something performs well, I tend to not hear anything. If something performs poorly, or costs too much, I'm the person who gets called to account for it and I'm the person who has to make the changes to correct it.
