Choose ConvertKit if your welcome letter needs to feel personal, simple, and creator friendly. Choose Mailchimp if you want polished templates, store tools, and more design control. Both can send a great automated welcome email, but they shine for different people.
TLDR: ConvertKit is best for writers, coaches, podcasters, and solo creators who want a clean welcome sequence without fuss. Mailchimp is better for ecommerce brands, teams, and anyone who wants pretty layouts with product blocks. For example, if 1,000 people join your list and your welcome email gets a 55% open rate, 550 people may see your first offer, story, or freebie. A simple ConvertKit flow may take 10 minutes to build, while a more designed Mailchimp email may take 25 minutes but look fancier.
What is a welcome letter, really?
A welcome letter is the first email a new subscriber gets from you.
It says, “Hey, you made it.”
It may deliver a free guide. It may introduce your brand. It may share your best blog post. It may offer a discount. It may just make the reader smile.
That first email matters a lot. People are most interested right after they sign up. Wait too long, and poof. Their attention runs away to cat videos and lunch plans.
A good automated welcome email should do three things:
- Arrive fast. Ideally within minutes.
- Sound human. Not like a robot in a blazer.
- Point to one action. Click, reply, buy, read, or download.
Mailchimp: the friendly toolbox with lots of buttons
Mailchimp is famous for email marketing. It has been around for ages. Many people try it first because the name is everywhere.
For welcome emails, Mailchimp gives you nice templates. You can drag in images. You can add buttons. You can use brand colors. You can build emails that look like mini web pages.
This is great for shops, local brands, nonprofits, and small teams. If your welcome email needs a coupon, product photos, or a bright hero image, Mailchimp feels natural.
Mailchimp is strong at:
- Pretty email templates
- Drag and drop editing
- Basic store connections
- Product blocks for ecommerce
- Reports with clicks, opens, and sales data
- List growth forms and landing pages
It also has customer journeys. That is Mailchimp’s automation builder. You can send one welcome email or a full series. For example:
- Send welcome email right away.
- Wait 2 days.
- Send a product guide.
- Wait 3 days.
- Send a discount reminder.
Nice and useful.
The annoying bit? Mailchimp can feel crowded. There are menus inside menus. Sometimes you just want to send one clean welcome email, and suddenly you are clicking around like you lost your keys in a grocery store.
ConvertKit: the calm choice for creators
ConvertKit is built for creators. Think writers, course sellers, YouTubers, artists, and coaches. It focuses less on fancy design and more on clear email that sounds like a real person wrote it.
That is good for welcome letters.
Why? Because many welcome emails work best when they feel like a note from a human. Not a glossy flyer.
ConvertKit makes this simple. You create a form. You write an email. You set the automation. Done.
ConvertKit is strong at:
- Simple automation flows
- Plain text style emails
- Tagging subscribers by interest
- Creator friendly funnels
- Email sequences
- Easy freebie delivery
Let’s say you offer a free “7 Day Meal Plan.” Someone signs up. ConvertKit can tag them as meal plan subscriber, send the PDF, then start a 5 email welcome series.
That can be built fast.
Honestly, it feels like ConvertKit was made for people who hate fiddling with design boxes for 40 minutes just to say hello.
Ease of use: who wins?
For a basic welcome email, ConvertKit wins.
It is cleaner. It has fewer distractions. The automation builder is easy to understand. You can see what happens after someone signs up.
Mailchimp is still friendly, but it has more stuff. More tabs. More settings. More choices. That can be helpful later. At the start, it can slow you down.
If you are sending your first welcome letter today, ConvertKit may feel faster.
If you care about layout, images, columns, buttons, and product rows, Mailchimp may feel better.
Email design: who looks better?
Mailchimp wins for visual design.
Its templates are more polished. You can make a welcome email that feels like a colorful magazine page. That helps if you sell clothes, candles, food, art, or anything visual.
ConvertKit keeps things simple. Its emails often look more like personal notes. This can be a strength. Plain emails can feel warmer. They can also avoid that “big marketing blast” smell.
Pick based on your brand:
- Visual brand? Mailchimp.
- Personal brand? ConvertKit.
- Online shop? Mailchimp.
- Newsletter or course? ConvertKit.
Automation: who handles welcome sequences better?
Both tools can send automated welcome emails. Both can send multi email sequences. Both can wait a few days between emails.
ConvertKit feels smoother for creator funnels. You can tag people, move them through a sequence, and send different emails based on what they click.
Mailchimp has strong customer journeys, especially if you connect a store. You can trigger emails based on purchases, abandoned carts, or product interest.
So the winner depends on your goal.
Use ConvertKit if:
- You want to welcome subscribers to a newsletter.
- You sell courses, downloads, coaching, or memberships.
- You want simple tags and clean sequences.
Use Mailchimp if:
- You run an ecommerce store.
- You want product based welcome emails.
- You need heavier design options.
Analytics: what can you track?
Both platforms show the basics. You can track open rates, click rates, unsubscribes, and subscriber growth.
Mailchimp often feels stronger for campaign reports. It can show ecommerce revenue if your store is connected. That is useful if your welcome email includes a 10% discount.
ConvertKit reports are simpler. That is not bad. You can quickly see if people opened, clicked, and joined a sequence.
Here is a simple example:
- 1,000 new subscribers join.
- 560 open the welcome email.
- 140 click the free guide link.
- 35 buy a $29 product.
That is $1,015 from one welcome flow. Tiny robot email. Big result.
Pricing: what should you expect?
Pricing changes, so always check the current plans. Still, the pattern is clear.
Mailchimp can start cheap for small lists, but costs may rise as contacts grow and features unlock. Some automation and testing tools sit on higher plans.
ConvertKit is often simple for creators, but it can also get pricey as your list grows. The free plan may be enough to start, but serious automation usually means upgrading.
The real question is not, “Which is cheaper?”
The better question is, “Which one helps me send faster and earn sooner?”
