Mailchimp Deliverability Alternatives

If Mailchimp emails are going to spam, switching platforms usually isn't the answer. Here's what actually fixes it.

The real issue: When Mailchimp campaigns land in spam, most people assume it's a Mailchimp problem. In most cases it is not. The cause is usually misconfigured SPF, DKIM, or DMARC records in your domain's DNS. These records exist on your domain, not inside Mailchimp - so switching to a different platform will not fix the problem. The DNS authentication problem follows your domain wherever you go.

Fix Mailchimp deliverability before switching platforms

The most common Mailchimp deliverability problems - and their fixes:

  • SPF not set up - Your SPF record must include include:servers.mcsv.net. If it is missing, receiving mail servers cannot confirm Mailchimp is authorized to send for your domain.
  • DKIM CNAME not published - Mailchimp provides CNAME records for DKIM that you must publish in your DNS. Many accounts have Mailchimp "configured" but the CNAME never made it to DNS.
  • No DMARC record - Gmail and Yahoo now require DMARC for bulk senders. A missing DMARC policy means your authentication is incomplete regardless of SPF and DKIM.
  • Sending from a free email address - If your Mailchimp From address is @gmail.com, @yahoo.com, or any free email domain, DMARC alignment fails and spam placement increases dramatically.

When switching from Mailchimp actually makes sense

Once DNS authentication is confirmed correct, there are legitimate reasons to switch sending platforms:

  • Cost - Mailchimp pricing scales steeply with list size. At 10,000+ contacts, alternatives can be significantly cheaper.
  • Dedicated IPs - If you send high volume (500,000+ emails/month), dedicated IPs give you full control over your sending reputation. Mailchimp only offers dedicated IPs on paid plans.
  • Automation features - Some platforms (Klaviyo, ActiveCampaign, Brevo) have more advanced behavioral automation and segmentation than Mailchimp.
  • Transactional email - Mailchimp is primarily for marketing campaigns. If you also need transactional email (receipts, password resets), a dedicated transactional service like Postmark or Mailgun may be better.

Amazon SES Lowest cost at high volume - requires more technical setup 3,000/day from EC2 $0.10 per 1,000 emails

What you need to fix regardless of platform

Whether you stay with Mailchimp or switch to any alternative, your domain still needs correctly configured authentication. Every platform provides DKIM records to publish - but SPF and DMARC are your responsibility.

Update SPF when switching

Each platform has its own SPF include. When you switch from Mailchimp, remove include:servers.mcsv.net and add your new provider's include. Use the SPF Generator to rebuild it correctly.

Replace DKIM records

Delete Mailchimp's DKIM CNAME records and publish your new provider's DKIM. Use the DKIM Checker to verify the new records are live.

Keep DMARC in place

DMARC lives on your domain and works with any sending platform. If you do not have one yet, use the DMARC Generator to create it before or during your migration.

Frequently asked questions

Will switching from Mailchimp to Klaviyo or Brevo fix my deliverability?

Only if the cause is specific to Mailchimp's infrastructure or pricing. If your emails go to spam because SPF, DKIM, or DMARC are misconfigured, the same DNS authentication problems follow your domain to any new platform. Fix authentication first - run an InboxGreen check to confirm your DNS is correct before migrating.

What SPF record do I need if I switch away from Mailchimp?

Remove include:servers.mcsv.net and add your new provider's include. For Klaviyo: include:klaviyomail.com. For Brevo: include:spf.sendinblue.com. Check your new provider's documentation for the exact SPF include value. Use the SPF Generator to rebuild the record with correct syntax.

Does Mailchimp have a spam problem?

Mailchimp is a legitimate ESP with strong deliverability infrastructure. Spam placement from Mailchimp campaigns is almost always a sender-side problem: missing authentication, poor list quality, high complaint rates, or sending from a free email domain. Run an InboxGreen check to confirm authentication is correct before drawing conclusions about the platform.

I'm using a Gmail address as my Mailchimp From address - is that the problem?

Yes, very likely. Gmail and Yahoo enforce DMARC, which requires the From address domain to align with the authenticated sending domain. When you send Mailchimp campaigns from [email protected], the DMARC alignment fails because gmail.com is not the domain Mailchimp authenticates on your behalf. Switch to a From address on a custom domain (e.g. [email protected]) and set up authentication on that domain.
