When Mailchimp jacks up your monthly bill for crossing a contact limit, switching tools saves real cash. Prepping your subscriber files correctly lets you migrate from Mailchimp to AWeber in one afternoon without losing paying buyers or dropping your inbox rates.
The Short Version
- Export only subscribed contacts from Mailchimp so you don’t pay for dead emails or hurt your score.
- Add three CNAME records to your DNS host to pass modern inbox checks before sending mail.
- Rebuild your main welcome series and warm your domain with a short note to your best readers.

Isolate Clean Contact Records Before You Export
Mailchimp uses a billing setup that can easily catch you off guard. The company charges you for every contact on your list, including people who left months ago. It even charges you for shoppers who bought once through a checkout integration but never opted into your marketing. If you export your whole list without filtering, you pay your new email tool for dead weight.
Start your export in Mailchimp by clicking your audience tab. Choose Export Audience to begin. The system builds a zip folder for you to download. Open that folder on your computer before touching your new account.
Inside that folder, you only want the file named subscribed members. Delete the sheets with unsubscribed and cleaned addresses so you never upload them by mistake. Putting dead contacts into a new tool breaks anti-spam rules. It also hurts your sender score right away.
I always recommend taking ten minutes right now to prune inactive email subscribers who haven’t opened a message in three months. Cutting cold leads keeps your list lean. It stops you from paying for a higher plan than your business needs.
How to Migrate Mailchimp to AWeber Without Contact Loss
Once you save your list, log into AWeber. If you have under 500 contacts, the free tier gives you basic sending and one welcome sequence. For bigger lists, check the real numbers on the AWeber pricing breakdown. This keeps your monthly costs clear before you move your files.
Follow these steps inside your dashboard to import your contacts cleanly:
- Open the import tool: Select your target list from the active list dropdown, click Subscribers on the left menu, choose Add Subscribers, and pick Import Multiple.
- Upload your data: Drag your clean CSV file directly into the upload area to launch the column mapping window.
- Map fields and tags: Match your email and name columns first, use Add New Field for custom data, and map your tags column straight to AWeber tags so your audience groups stay intact.
- Set your update rules: Choose Add new and update existing subscribers so contacts already in your account receive fresh tags without creating duplicate records.
- Confirm list permission: Answer the short opt-in confirmation questions to verify list compliance, then click submit to finish processing.
Here is how Mailchimp and AWeber stack up on billing rules, DNS setup, and monthly costs.
| Feature / Billing Rule | Mailchimp Reality | AWeber Setup |
|---|---|---|
| Billed Contact Types | Billed for unsubscribed and inactive contacts | Only active subscribed contacts count |
| Entry Paid Plan | Starts at $13/mo for 500 contacts | Starts at $15/mo Lite ($12.50/mo annual) |
| Domain Authentication | Static TXT records | 3 CNAME records with auto key rotation |
| Free Tier Limit | 250 contacts, 500 sends/mo, no automations | 500 contacts, 1 list, automations included |
| Overage Penalties | Automatic tier jumps with unexpected price spikes | Predictable flat subscriber tier brackets |
Authenticate Your Domain and Rebuild Automated Workflows
Big inbox providers like Google and Yahoo block mail from unverified domains. You must prove you own your domain so your notes avoid the spam folder. Both inbox providers use strict DMARC authentication rules to drop messages from unknown senders without warning. Setting up your DNS records stops this headache.
Head to Domains and Addresses inside your AWeber account settings. Find your sending domain on the list. You need to publish the following records where your domain lives:
- Add three DKIM records: Create three new CNAME records using the exact hostnames and keys provided by AWeber so the system can rotate security keys automatically.
- Set Cloudflare to DNS only: Turn off the orange proxy cloud if you use Cloudflare so the record stays set to DNS only.
- Add your DMARC record: Create a single TXT record with the host set to _dmarc and paste a standard monitoring policy string.
AWeber handles SPF alignment on its own mail servers. You don’t need to add a custom SPF string to your domain panel.
Once your DNS panel shows green checks in AWeber, rebuild your automated emails. Open the Campaign builder and craft a quick welcome note. Check the AWeber review to see how its visual campaign builder stacks up against other tools. You can test your welcome campaign inside AWeber before your first send.
Warm Your Domain and Send Your First Broadcast
Switching email tools changes the mail servers that send your notes. If you blast five thousand people on day one from a new account, spam filters get suspicious. You need to warm your new setup by writing to your most active readers first.
Build a quick segment of subscribers who opened or clicked an email in the last thirty days. Send them a short, helpful note letting them know you upgraded your mail setup to fix delivery. Ask a simple question or share a link to get quick replies and clicks.
Leave your old Mailchimp account open for two weeks after your first send. That gives your old links time to work and lets any active automations wrap up. Once your open rates look solid in AWeber, you can cancel your old plan for good.
Frequently Asked Questions About Migrating from Mailchimp to AWeber
Will my subscribers have to opt in again when I switch to AWeber?
No, you don’t need to make your readers sign up again. During the import wizard, pick the option confirming that these people already gave you permission to email them.
Does Mailchimp charge me for people who unsubscribed?
Yes, Mailchimp counts unsubscribed and non-subscribed contacts toward your billing limit until you delete them. That extra fee is why many site owners leave Mailchimp to save cash.
What happens to my custom tags during the move?
Your tags move over fine as long as they sit in their own column in your CSV file. Just map that column to the Tags field inside AWeber when you upload your sheet.
How long does it take for AWeber DNS records to verify?
Most DNS changes go live in thirty minutes to a couple of hours. In rare cases, global DNS updates can take up to a full day before the green checkmarks appear.
Can I run Mailchimp and AWeber at the same time during the move?
Yes, keeping both accounts open for a week or two is a smart move. It keeps your live signup forms working while you check your new DNS settings and campaigns in AWeber.
What is the biggest mistake people make when exporting from Mailchimp?
The top mistake is uploading the full zip folder without separating the sheets. Only upload the subscribed members file so you avoid adding bad emails and unsubscribes.
Do I need to set up a custom SPF record for AWeber?
No, AWeber handles SPF alignment on its own sending mail servers. You only need the three DKIM CNAME records and one DMARC TXT record in your domain panel.
