Objective:
Explore and implement Odoo's email marketing capabilities for customer outreach campaigns.
Initial Campaign Setup:
Created a test campaign: "Little League Winter 2026"
Performed data hygiene on contact database:
Removed invalid email addresses
Eliminated duplicate contact records
Initial contact database: 393 records
Successful deliveries: 68 emails
Failed deliveries: 325 emails (blocked by Zoho SMTP restrictions)
Current Infrastructure Analysis:
Outgoing Email Server: Zoho SMTP
Identified Limitation: Zoho's SMTP service imposes restrictions on bulk marketing email volumes
Zoho Support Recommendation: Zoho Zeptomail
Zeptomail Assessment:
Suitable for transactional emails (OTP, invoices, notifications)
Not designed for marketing campaign bulk sending
Alternative Solutions Evaluated:
Zoho Campaigns:
Requires contact list migration to Zoho platform
Creates data silo separate from Odoo CRM
SendGrid:
60-day trial period available
Post-trial conversion to paid plan required
Previous "Essential Forever Free" plan discontinued for new users
MailChimp:
Free tier available for bulk email sending
Limited Odoo integration capabilities
Requires manual contact synchronization
Mailjet:
Remaining viable option with Odoo compatibility
Offers direct SMTP integration
Maintains contact data within Odoo ecosystem
Technical Constraints:
Zoho SMTP server blocks bulk marketing emails to prevent spam flagging
Need for dedicated email marketing service provider
Requirement for seamless Odoo integration
Next Steps:
Implement Mailjet integration for email marketing campaigns
Maintain Zoho SMTP for transactional emails (invoices, notifications)
Establish dual-email strategy for optimal deliverability
Conclusion:
Current Zoho SMTP infrastructure insufficient for marketing email volumes. Mailjet identified as most suitable alternative for Odoo-integrated email marketing while maintaining Zoho for critical business communications.
