If you are using MailerLite and Odoo and wanted to connect both, now you can use Mailerlite connector to do that.
This connector can sync MailerLite groups, subscribers and campaigns with Odoo Mailing Lists, Mailing Contacts and Mailings. It also supports MailerLite webhooks for more up to date data sync.
More info about connector can be found here.
