There are 3 simple steps to successful integration of SendForensics with Mailchimp:
The SendForensics system needs to become another recipient of your emails to be able to analyze your deliverability properly:

To do this, first locate your unique SendForensics analysis address within your SendForensics account (Account > Addresses):

Now copy this unique analysis address and add it as a new contact within your Mailchimp account (Audience > Add contacts, Add a subscriber).

Now whenever you send a marketing email within your Mailchimp account, make sure this contact is always included and the SendForensics system will receive a live copy for analysis.
Note: You might like to create a new tag for the address under something like "Deliverability Testing" so it is easy to add to sends.
To enable the MailChimp plugin, you will need to generate an api key in your MailChimp account.
There are detailed instructions available here, but to get started quickly, simply follow the steps below.
1. Log into your MailChimp account, click on your Account icon on the bottom left and choose "Profile".

2. On the Profile page, click on the "Extra" dropdown and choose "API key".

3. On the API key page, copy an existing key or generate a new API key by clicking "Create A Key".

4. Login to your SendForensics account, visit the Domains Settings page.
5. Click on the desired domain, and go to "ESP Integrations".
6. Go to "ESP Integrations", "Add Plugin" and select "MailChimp". Paste the API Key and click Activate Plugin.

Each time you create a new campaign and are ready to send live, first send a test to your unique SendForensics analysis address for pre-emptive deliverability analysis:

After receiving it, the system will process your email and display the full deliverability analysis results within your (SendForensics) dashboard.
Cycle through the tabs following the advice and recommendations to optimize the deliverability of your email as much as possible, re-testing as necessary. When you have reached a comfortable deliverability score (vs amount of work needed to improve it further), the campaign can be sent live.
Live sends will also be processed (as a result of Step 1 above), and will additionally contain an analysis of your engagement data (live results) to produce advice and recommendations on any deliverability issues hidden within. These can be acted on and corrected before the next live send by following the instructions and guides within the SendForensics dashboard.
Note: Engagement data from Mailchimp is pulled in for analysis once per day, so there may be a delay between activating the plugin and receiving the first batch of data.
