Mailchimp vs Sendy for Tree Service Marketing (2026)

The Bottom Line: Mailchimp is the easiest out-of-the-box email tool for a tree service owner who wants drag-and-drop design. However, if your company has been around for 10 years and you have a list of 5,000+ past clients, Mailchimp becomes incredibly expensive. Sendy solves this by routing emails through Amazon SES, dropping your monthly cost to literally pennies, but it requires a technical setup.

1. The Cost of Scaling an Email List

The biggest marketing asset a tree care company has is its historical customer list. When January hits and the schedule dries up, sending a single “Winter Canopy Pruning Discount” email to 4,000 past clients can instantly fill your board for the month.

Mailchimp penalizes you for having a large list. If you have 5,000 contacts, Mailchimp will charge you roughly $75 to $100 every single month, regardless of whether you actually send an email that month.

Sendy is a self-hosted application. You buy the software once (around $69) and connect it to Amazon Simple Email Service (SES). Amazon charges you $0.10 per 1,000 emails. If you send that same blast to 5,000 people, it costs you 50 cents. It is the ultimate operational loophole for seasonal businesses.

2. Ease of Use vs. Technical Friction

The trade-off for Sendy’s incredibly low pricing is the installation. You have to install Sendy on your own web server (like a WordPress site) and configure DNS records for Amazon AWS. If you do not have a web developer, this will be highly frustrating. The user interface is also very bare-bones—it looks like a dashboard from 2012.

Mailchimp, on the other hand, is built for the average office manager. It has beautiful drag-and-drop templates. You can easily drag a photo of a crane removal into the email, add your logo, and hit send in under 15 minutes. There are no servers to configure.

3. Automation & Tree Service Workflows

Tree services need specific automations. For example, if a homeowner downloads a “Tree Care Guide” from your website, you want them to automatically receive a sequence of emails establishing your authority before your arborist arrives for the estimate.

Mailchimp dominates here. Their visual “Customer Journey” builder allows you to set up complex rules: “If they open this email, wait 2 days and send Email B. If they don’t open it, send Email C.”

Sendy only features basic autoresponders. You can tell it to send a sequence of emails (e.g., Day 1, Day 3, Day 7), but it lacks the advanced behavioral triggers that modern marketing agencies rely on.

4. The Final Verdict

If you have an office manager who needs to quickly design beautiful storm-prep newsletters and you don’t mind paying a premium for convenience, Mailchimp is the industry standard for a reason.

However, if you are a sharp operator with a massive list of 5,000+ past clients, and you only send out 3 or 4 seasonal blasts a year (Spring fertilizing, Hurricane Prep, Winter Pruning), Sendy will save you over $1,000 a year in subscription fees. Just hire a developer on Upwork for $50 to set up your Amazon SES connection, and enjoy practically free email marketing.
