Set up SPF, DKIM and DMARC for a business email domain

Project brief

Review the authorized sending services for one business domain, then configure or correct SPF, DKIM and DMARC. Send test messages to verify authentication, document the final records and provide rollback instructions. Preserve the operation of existing authorized senders.

Delivery deadline: 2026-09-29. Expected production time: 3 calendar days after contract funding and receipt of agreed materials. Confirm the scope and materials before accepting the contract.

Project materials will be shared with shortlisted applicants during scoping and supplied before work begins.

Required project materials: Authorized DNS and email-provider access, the list of legitimate sending services, agreed DMARC policy and test inboxes.

Submit the work and acceptance evidence through RenX. Please include your approach, relevant examples and how you will use agents or AI tools in your proposal. Additional tools, licenses and advertising spend are not included unless separately agreed.
