Connect email providers & grow your list
Automatically subscribe users to your newsletter when they opt in while using Allspice on your site.

Overview
Allspice allows publishers to automatically add users to their newsletter when those users explicitly opt in while using Allspice on your site.
When a visitor creates an Allspice account - or logs into an existing Allspice account - they will see an option to join your newsletter. If they agree, Allspice securely sends their information to your connected email marketing provider(s).
You can connect multiple providers at once. For example:
- Mailchimp + Kit simultaneously
- MailerLite + Mailchimp
- All three providers together
If a user consents, Allspice will attempt to subscribe them to every enabled provider linked to the domain.
If you need an additional email provider supported, please contact Allspice support.
Where to Configure This
- Open the Publisher Portal
- Navigate to Domain Settings
- Scroll to Link Email Providers
- Click + Add Provider
You will then:
- Select the provider
- Enter required credentials
- Choose the list / audience / group / tag
- Save
Your credentials are stored securely and encrypted.
User Experience
Users may be prompted to join your newsletter when:
- Creating an Allspice account on your site
- Logging into an Allspice account on your site
- Returning to your site with an existing Allspice account
If they agree:
- ✔ They are subscribed to your configured email list(s)
- ✔ Only the domains they consent to are subscribed
- ✔ Consent is recorded and timestamped
If they do not agree:
- ✖ No subscription occurs
- ✖ No provider is contacted
Provider Setup Instructions
Mailchimp
Where to get API Key
- Log into Mailchimp
- Profile → Extras → API Keys
- Click Create Key
- Copy the key
You will also need your Server Prefix (example: us18, us19)
This appears at the end of the API key:
In Allspice:
- Enter the full API key
- Enter the server prefix
- Select your Audience
How subscriptions work
Users are added to the selected Audience. You may later segment them using Mailchimp tags or automations.
MailerLite
Where to get API Token
- Log into MailerLite
- Integrations → API
- Click Generate New Token
- Copy the token
In Allspice:
- Paste the token
- Select the Group to subscribe users into
How subscriptions work
Users are added to the selected Group. Groups are the correct MailerLite concept for subscriber entry - campaigns are not direct subscription targets.
Kit (formerly ConvertKit)
Where to get API Key
- Account Settings
- Developer
- Add New V4 Key
- Copy the value
In Allspice:
- Paste the key
- Select a Tag
How subscriptions work
Users are subscribed to the chosen Tag. You can then build automations inside Kit triggered by that tag.
Managing Providers
Inside the Publisher Portal you can:
Enable / Disable
Temporarily stop subscriptions without deleting configuration.
Edit
Update credentials or change the destination list/group/tag.
Multiple Providers
If multiple providers are enabled:
- Allspice attempts all subscriptions
- Failure of one provider does not block others
Data Sent to Providers
Only minimal data required for subscription:
- Email address
- First name (if available)
- Last name (if available)
Consent is recorded by Allspice but not transmitted unless the provider supports it.
Security
- Credentials stored encrypted
- Never exposed to client browsers
- Sent server-to-server only
- Only triggered after explicit consent
Troubleshooting
Subscribers not appearing?
- Confirm provider is enabled
- Confirm destination selected
- Confirm valid API key
- Confirm automations not filtering the user
Changed lists recently?
Re-open provider settings and re-select the destination.
