Would like to be able to upload my own business fonts. Would like to be able to manage list uploads and exports and segmenting without having the highest authority level as we are often asked to troubleshoot and check on set-up and segmentations which clients often get concerned giving us access to the other features of the Manager role.
Mailchimp is very sensitive to deliverability, which is part of what makes it great, but also part of what makes it a difficult tool for new brands to use to grow their list at a cost-effective rate. Our company gets top-of-the-funnel leads for clients, whereas Mailchimp really wants middle-of-the-funnel or more qualified leads. Their customer support doesn't really care about your past relationship with them. The moment a Mailchimp user gets a high unsubscribe rate or spam-reporting Mailchimp immediately demands the brand to delete ALL of the emails regardless of their engagement. I worked with a brand that had to delete all 20,000 of their subscribers because they had 1 person file a direct complaint against the brand, which cost the company so much they ended up switching ESPs when Mailchimp refused the budge.
I hate that you can't send one email campaign to multiple lists. And Mailchimp does not have a simple way to segment current subscribers from multiple lists into one Master List other than exporting all the contacts and adding the original list name as a Merge Tag (like the partnership that drove those emails or marketing campaign that sparked their sign-up). It makes more sense to segment, but often we get clients after they've started with the Multi-List strategy and it is more a headache than it is worth to restructure the CSVs to create one Master List.
Mailchimp is best for small-mid size businesses getting started on growing their business. It is relatively easy to figure out, and provides very understandable analytics. I think of it as a great internship to the world of Email Marketing, where brands can test what works best for them and then as they scale and grow to develop a larger email marketing budget they can invest in a more advanced platform.
Our clients use our services for list growth, and then Mailchimp to nurture those new leads into conversions.
It is great that Mailchimp can scale to the skills and needs of the clients from little email marketing expertise to entire teams devoted to coding and content writing.
