Here is a guide on how to connect your MailChimp SMTP with Warmup Inbox.
1) In your MailChimp account, go to Automations and choose Transactional Emails. In the Transactional Emails click on Launch App.
2. Go to the Settings - Sending Domain and add your domain and make sure it´s verified, and you have valid DKIM and SPF records.
3. In the top bar, click on the SMTP & API Info. Then, click on Add API key
4. Click on the New API key button and in the description type: WarmupInbox
5. Click on the Create API key and create your API key. You will use it as the SMTP password.
6. Go to the Warmup Inbox, click on the Add Inbox button, and choose the SMTP Only option.
Email address: the email address you´ll be sending from in Mailchimp
SMTP username: the email address you´ll be sending from in Mailchimp
SMTP password: use the generated API key
SMTP host: smtp.mandrillapp.com
SMTP port: 587
SSL/TLS: NO
Once you have this information, you can get set up on Warmup Inbox by selecting the SMTP-only option.
Please note, that you can use the SMTP Only option only if you have purchased the Send-only plan.
Alternatively, you can find your IMAP in your email provider settings and connect the SMTP with IMAP accordingly:
SMTP & IMAP Option
With the trial, Basic, Pro, and MAX plans, you can connect your MailChimp account only when creating an IMAP connection.
The email address for the IMAP connection must be the same email address as the one you specified in the SMTP.
In this case, instead of using the SMTP Only option, you will connect your inbox using the SMTP & IMAP option.
For the IMAP part, you will need to gather this information from the inbox that will be receiving emails :
IMAP username: the email address of the inbox that will be receiving emails
IMAP password: the password from this inbox. If it´s a Google inbox, you will need to create an app password and use it instead of the regular password from your inbox.
Here are the instructions:

IMAP host:
IMAP port: typically 993 (or you can use 143)
SSL/TLS: using port 993 - ON, using port 143 - OFF
Note: the SMTP/IMAP option doesn´t work with Office365 accounts as they disabled the Basic authentication in 2023.
