How do I plug Stripo / Unlayer HTML into Odoo campaigns?

The module adds a *"Custom Email Code" wizard*. You paste the finished HTML (from Stripo, Unlayer, BEE Free etc.) as plain text and click /Apply/. Before overwriting, the existing body_html is automatically backed up to custom_body_arch , so you can always roll back. /Code reference:/ models/mail_marketing_wizard.py lines 9–16 apply_email_code : if not mail_template.custom_body_arch: mail_template.custom_body_arch = mail_template.body_html , then mail_template.body_html = self.email_code .

Can I switch between original and custom body?

Yes. The *use_custom_code* toggle on the mailing record switches between the two stored versions. When active, body_html is set to the custom code; when disabled, the original body is restored. Handy for A/B testing custom vs. stock layouts. /Code reference:/ models/mail_marketing_wizard.py lines 27–36 _onchange_use_custom_code with two branches ( self.body_html = self.custom_body_html vs. self.body_html = self.custom_body_arch ).

Which fields are stored on mailing.mailing?

Four new fields: *custom_body_html* (your Stripo/Unlayer code), *custom_body_arch* (backup of the original), *use_custom_code* (toggle) and *custom_code_applied* (marker indicating it has been applied at least once, used to avoid duplicate backups). /Code reference:/ models/mail_marketing_wizard.py lines 19–25: _inherit = 'mailing.mailing' with the four fields; custom_code_applied default is False .

Where do I launch the Custom HTML wizard?

From a mass mailing form (model mailing.mailing ). The wizard button opens a mail.marketing.wizard transient modal with a multi-line /Email Code/ text field. The active_id in the context references the campaign whose body will be replaced. /Code reference:/ models/mail_marketing_wizard.py lines 3–7: _name = 'mail.marketing.wizard' , field email_code = fields.Text(string="Email Code", required=True) ; line 10 mail_template = self.env['mailing.mailing'].browse(self.env.context.get('active_id')) .
