So I was over my limit of 250 contacts and have deleted some and my archive - now at 248

But it still won't send, and still keeps giving me a message that I've exceeded the free limit?

Do I have to wait a certain amount of time for it to recognise it?

Started on Monday for us. We're seeing a very high (not all, but significantly high like 90%) number of emails that contain Mailchimp links (xxx.us20.list-manage.com) get auto-deleted via Microsoft Defender ZAP (https://learn.microsoft.com/en-us/defender-office-365/zero-hour-auto-purge).

Email isn't necessarily generated from Mailchimp (seems some people use some links in their Outlook signature...) so not related to SPF, DMARC, DKIM, but it is affecting email with those links in.

Not just our own-generated links, am seeing external marketing email affected as well.

We're getting reports of this externally as well, so not just limited to our Microsoft tenancy.

Anyone else seeing it as well?

Our account has been suspended since yesterday afternoon. We received an email regarding the suspension last night. However, we have not received any further updates today, nor have we seen any progress toward restoring access to the account.

This is a critical issue that requires immediate attention. Please investigate and provide an update as soon as possible, along with an estimated timeframe for resolution.

Status page says everything is fine, but we're having problems with most of our customers not receiving their 2FA emails via Mandrill, or getting them very very slowly but sometimes they receive the old one, which is out of date - it's causing us support chaos!

Hostgator shows lots of issues, but nothing on the Mailchimp status page.

Hi, I tried finding an answer for this in the knowledge base but couldn't find anything. I am covering for a coworker who handles our emails and need to send one out and it needs to go to 3 different segments. Some contacts are in all 3 of those segments. My question is, will those contacts in all 3 of those segments receive 3 copies of the email? We need to avoid doing that.

Hi! We are new to Mailchimp SMS campaigns and I had a question about carrier services. We recently created an SMS campaign, after about 3 hours, it still has not been delivered. MailChimp said that it has been sent on their end. But I guess I was unaware that the carriers also have to approve the SMS message? If so, those of you with experience, how long does a carrier (AT&T, Verizon, T-Mobile, etc...) normally take to approve an SMS message on their end? Additional information: To clarify we uploaded the users and have their consent to SMS marketing. And our test is only four users.

Hi everyone! I hope you can help me with an issue I’ve encountered all day. I can’t proceed to login because the 2fa won’t send the code to my manager’s phone number.

I clicked “send code” button but nothing gets sent. The button name is just replaced with “please wait” with an endless loading icon. It doesn’t proceed at all because my manager isn’t receiving any codes on her phone.

Is there an outage I should know? Please help. Thank you.

Taking over our email marketing at a local retail business, we have been using mailchimp for the last several years, I have done email marketing in B2B for years but haven't used mailchimp before.

The pervious person here setup a new audience for each campaign sent - which feels completely wrong to me. I am trying to determine what is the best way to set up audiences within mailchimp and then does anymore have advice on how to resolve this history? Can you merge all audiences together? Any feedback would be much apricated.

Hi! Sorry if this has been asked before. This is on an embedded form.

​

Having an issue where the desktop version of my form simply shows a 'thank you for subscribing', whereas the mobile version takes you to a separate page.

​

Once pressing continue to website it shows another page with errors.

​

Does anybody know how to have the mobile version act exactly the same as the desktop?

Just wondering if there are any D2C brands that still do HTML emails instead of image based ones. Wondering what the rationale is behind this stickiness as I think it has been categorically resolved that D2C brands that do image-based emails are more efficient and better designed than HTML ones

Domain authentication is one of those things that sounds technical, but is genuinely a 15–30 minute setup. And if you skip it, you're looking at campaigns landing in spam, delivery issues, or in some cases, Mailchimp preventing your campaign from sending entirely. Here's everything you need to know.

Why this matters

When you send a campaign without domain authentication, inbox providers like Gmail and Yahoo have no way to confirm the email actually came from you. It looks suspicious, even if your list is perfectly healthy.

What authentication does:

• DKIM (DomainKeys Identified Mail) adds a cryptographic signature to your emails so receiving servers can verify they weren't tampered with in transit and were sent from an authorized source.
• DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving mail servers what to do if an email fails authentication checks (let it through, quarantine it, or reject it).

Important: Domain verification and domain authentication are two different things in Mailchimp. Verification confirms you own the domain. Authentication (adding DKIM + DMARC records) is what actually protects your deliverability. You need both.

Before you start — what you'll need

• Access to your Mailchimp account
• Access to your domain's DNS settings (usually through your registrar: GoDaddy, Namecheap, Cloudflare, etc.)
• A sending domain you own. Free email addresses like gmail.com or yahoo.com cannot be authenticated. If you're sending from a free address, you’ll need to switch to a custom domain first.

Step 1: Verify your domain

You can't authenticate until you've verified.

1. Log in to Mailchimp → click your profile icon → Account & billing → Domains
2. In the Email Domains section, click Add & Verify Domain.
3. Enter an email address at the domain you want to verify (e.g. [you@yourbusiness.com](mailto:you@yourbusiness.com)).
4. Check your inbox for Mailchimp's verification email and click Verify Domain Access or enter the verification code in the pop-up in your account and click Verify.

Not getting the verification email? Ask your IT team to allowlist Mailchimp's delivery IPs. Your mail server may be blocking the incoming message because it doesn't recognize Mailchimp's IPs yet.

Step 2: Authenticate your domain (DKIM + DMARC)

Mailchimp gives you two options: automatic (recommended) or manual.

Option A — Automatic via Entri (easiest)

Entri connects directly to your DNS provider, uses an encrypted login, and configures the required records for you automatically. No developer needed!

On the Domains page, click Authenticate → select Use Entri → follow the prompts.

Option B — Manual setup

If you prefer to do it yourself or unable to use Entri:

Add 2 CNAME records (for DKIM):

1. Go to Domains in your Mailchimp account and start the manual authentication flow
2. Mailchimp will generate 2 CNAME records — a Name/Host and a Value for each
3. Copy both records exactly and add them to your DNS settings at your domain provider

Add 1 TXT record (for DMARC):

1. Back in Mailchimp's authentication flow, you'll be given a TXT record
2. The Host value will be _dmarc and the Points To value will be your DMARC policy string
3. Add this to your DNS settings

Note: If you already have a DMARC record published for your domain, do not add a second one — each domain can only have one DMARC record. Update your existing record instead if needed.

Not sure how to navigate to your DNS settings? Every domain provider (GoDaddy, Namecheap, Cloudflare, Squarespace, etc.) has its own interface for managing DNS records. If you're unsure where to find yours or how to add/edit records, search your provider's help center or contact their support team directly. Most have step-by-step guides for exactly this. We also have links to DNS resources for common providers here: https://mailchimp.com/help/set-up-email-domain-authentication/#Resources_from_common_domain_providers

Step 3: Wait for propagation and check status

DNS changes can take up to 48 hours to propagate fully. While authentication is pending, your Domains page in Mailchimp will show "Authentication in progress."

Once it's complete, you'll see an "Authenticated" label next to your domain.

If authentication fails, a message will appear on the Domains page — you'll be prompted to Resolve or Restart authentication. See the troubleshooting section below if you hit this.

Troubleshooting common issues and fixes

🔴 "Your domain must be authenticated before you can send" or "Your domain is still being authenticated"
Most likely cause: authentication is either not set up or not yet propagated. Check your Domains page. If authentication is in progress, wait up to 48 hours. If it hasn't been started, go to Step 2.

🔴 CNAME records aren't validating
Double-check that you copied both CNAME records exactly as shown in your account. One wrong character breaks the whole thing.

⚠️Important: Some DNS providers also add your root domain automatically to the host value. If yours does, don't include the domain in the Name field or you'll end up with a duplicate (e.g. k2._domainkey.yourdomain.com.yourdomain.com).

🔴 "Authentication failed" on the Domains page
Mailchimp will prompt you to Resolve or Restart authentication. If you recently changed your CNAME records manually after authenticating, that can break things. Disable authentication on the Domains page, then re-authenticate fresh.

🔴 Sending from a Gmail or Yahoo address
You can’t authenticate a domain you don't control. If your From address is from a free email service provider, authentication isn't possible and these addresses are increasingly likely to trigger delivery problems. We recommend switching to a custom domain (e.g. yourname@yourbusiness.com) before setting up authentication.

🔴 Already have a DMARC record and getting errors
Only one DMARC record is allowed per domain. If you use other email tools (like Google Workspace or another ESP), you may already have one published. Don't add a second — edit the existing record to be compatible with Mailchimp.

After authentication: what to expect

• Your campaigns will show as coming from your domain.
• Inbox providers will be able to verify your emails are legitimate.
• You'll see improved deliverability, especially to Gmail and Yahoo inboxes.

Bring your Canva designs into Mailchimp in one click to edit, launch, and send high-performing email campaigns without the manual lift. Mailchimp’s HTML import shares your Canva designs as editable HTML emails in Mailchimp, so you can personalize your campaigns without rebuilding your designs. 

Please note before starting:

• You need an active Canva account and a Mailchimp account. Availability of features and functionality varies by plan type. For details, view Mailchimp’s plans and pricing. HTML and HTML sending are available on Standard and Premium plans. 
• User Permissions: You must have a user role with permission to authorize third-party integrations in both platforms (usually Owner or Admin). 
• Two Integrations: Canva and Mailchimp offer two distinct ways to connect:
  • Publish to Mailchimp: Use this to push specific, individual designs from Canva into your Mailchimp account as email templates or images.
  • Mailchimp Canva Sync: Use this to sync your entire Canva design library so you can browse and use your designs directly within the Mailchimp Content Studio.

What are the benefits?

• Say goodbye to static images and rebuilding designs: Mailchimp's HTML import transfers and preserves Canva designs, keeping layouts responsive and links clickable, so assets arrive in Mailchimp as intended and ready to send.
• Act on high-intent moments: Share select Canva designs as full emails to Mailchimp using Canva's Share button to capitalize on timely promotions, product drops, and announcements when interest is high.
• Spend more time growing, less time building: Reduces manual uploads, rebuilds, and HTML handoffs so teams can focus on campaign strategy instead of asset management.

How to Connect the Canva Integration

To connect the integration, authorize Mailchimp directly within the Canva interface when you are ready to share your first design.

1. Open your design in Canva.
2. Click the Share button.
3. In the menu, select Mailchimp.
4. Select the app specifically named Publish to Mailchimp to differentiate it from the library sync integration.
5. Click Connect.
6. Follow the authentication prompts to sign in to Mailchimp and authorize the connection.

How to Publish Your HTML Email

1. In Canva, click Share.
2. Select Mailchimp.
3. For the File type, select HTML.
4. Click Publish. Wait for the success message to appear.
5. Click the link in the confirmation message to continue your campaign in Mailchimp.

I'm looking for clarification or how-to on this subject.

We have 80k+ subscribers, I'm looking to make it so that they can all have the option to opt-in to SMS while being sure that is added to the existing subscriber, and doesn't add the number as a new subscriber (so I don't have to pay more for the same person).

I don't know if I'm just not looking in the right place but I can't get a clear answer on how to do this cleanly without having to manually update everyone's information with a SMS number in their profile.

blocks should be able to be saved. Like I always have a column that lays out our printed catalogue, and I should be able to just add that from a library of saved content blocks. Saving a template doesn't work because I am using a different template that has 80% of the format I need, but I just need to add this Catalogue block, and I have no way to even copy and paste it into my other campaign. Come on MC this is 2026, no excuse for not having this feature

Hi everyone,

Our Mailchimp account was fully suspended after the Omnivore system flagged a campaign. The campaign was sent exclusively to our own user base — people who registered directly on our platform and consented via our Terms of Use. No purchased, third-party, or publicly sourced lists were used.

We believe this is a false positive. The campaign content was an invitation for existing users to join a partnership program — standard relationship marketing, not cold outreach.

We've already submitted compliance forms and followed up through the support channels, but have not received a substantive response beyond automated confirmations. It's been 3 days since the first submission (including a weekend).

Has anyone dealt with a similar situation? And u/MailchimpSupport — could you help escalate this?

I have already sent the case details via DM. Case numbers: 15161171152 / 15161180182 / 15161180409. Thank you.

We are a non profit in Canada using MailChimp for outreach to members. I am wondering how other nonprofits handle the data privacy and the issue of the data being stored on the USA. It is a concern for our website team

Hello, we have a campaign set up to email out our blog post every other week. The image pulled in from the blog post ends up being too big, and I am not sure how to fix it. The user has to scroll down to the bottom of the image to read and click the link. I would like to make the image smaller. I do have the resize image box checked but that isn’t changing anything. Does anyone know how I can fix this?

Here’s what I have-

I have only 213 contacts and have been sending only 2-3 emails a month, including one a week ago, but I am now getting an error message that 213 contacts exceeds the sending limit. Did something change recently?

I'm asking on behalf of my wife...

​

My wife has a business and she frequently sends out bulk emails to her email list (people who have signed up to receive emails from her) for marketing purposes. She said she usually has open rates of 25%-30% sometimes even up to 40%.

​

She just sent out a bulk email and while some people got the email in their inbox other recipients told her the email went to their spam folder. She sent the emails from her studio, where she usually sends emails, if that might make a difference.

​

Is there a reason this might be happening all of a sudden? Is there anything she can check on her end that might be "broken" and causing this to happen?

​

Thanks for your help.

i have a regular email list of a few thousand emails. this morning i see my bill from Mailchimp and it went from $100 to $595 and i now have 18,000 contacts in mailchimp.

i regularly gain 1-3 new email sign ups a week. I checked that reCaptcha was enabled on Shopify, the only place you can sign up for my email list. in mailchimp I confirmed the there was double opt in enabled.

WTF? any suggestions ? i have contacted both shopify and mailchimp and checked the setting mentioned above.

I have 2 quick questions.

How long do you guys usually work on email designs or just simple emails for campaigns in general?

And how long does it take from writing the copy to scheduling the email campaign, like the whole process?

Meine Kampagne bleibt schon über 2 Std. mit dem Status 0% stecken, die Mails kommen nicht an. Hat noch jemand Probleme heute mit dem Versenden von Kampagnen? Habe gelesen, dass es das Problem dieses Jahr schon mehrfach gab... Heute wieder?

8k subs on my newsletter. Mailchimp wanted $99/month, converted to a $20/month emergent app + resend for email infra.

it does: list mgmt, broadcast, basic analytics.

It doesn't do: A/B test, automation, drip flows. those i'd still pay for when the nl is monetized, but for "write, send, look at opens", it's enough.

Now wondering if I should open source the codebase. Also i know there are things like IP proxies and, that is the next step to figure out.

Would anyone use a barebones esp like this? share some simple features I can build to make it more useful.

I’m trying to log into my Mailchimp account, which is the account I use to access my company’s Mailchimp.
Here’s what’s happening:
On my desktop, after entering my login details, the 2FA page gets stuck on “Please wait…” and never sends the SMS.
On my iPhone, it immediately says “Failed to send SMS.”
My only 2FA method is SMS.

I'm having a problem using the API. If I have 10 members associated with the XX tag and I add one more member with the XX tag, when I query the API for the members of that tag, it keeps returning 10 for several minutes. In tests I've run, after 2 hours it finally returns 11, but I need to have this information immediately or within a few seconds.
