Laravel Dkim Laravel Package

Product Decisions This Supports

• Deliverability roadmap: DKIM signing is a prerequisite for credible transactional email (password resets, receipts, notifications, onboarding). This package lets you decide whether to solve deliverability in-app versus routing all mail through a managed provider (SES, Postmark, SendGrid) that signs on your behalf.
• Build vs. buy on email infrastructure: if the product requires per-tenant or per-domain sending identities (multi-tenant SaaS, white-label, custom domains), you need signing keys you control. This package makes "own our DKIM keys" a low-cost in-house option rather than a reason to buy an enterprise email platform.
• Laravel upgrade planning: v3.6.0 adds Laravel 13.x compatibility. This directly informs the "can we upgrade the framework?" decision — a dependency that lags a major Laravel release becomes a blocker on the upgrade roadmap. This release removes that blocker for the next major.
• Feature enablement: anything that depends on trusted sender identity — custom sending domains per customer, branded "from" addresses, SPF/DKIM/DMARC alignment for compliance-driven buyers (financial, healthcare, EU customers) — is unblocked without new vendor contracts.
• Risk/ops decision: signing in-app means key storage, rotation, and per-domain config become your operational responsibility. That trade-off belongs in the roadmap conversation, not the backlog.

When to Consider This Package

Consider it when:

• You send mail from Laravel and want DKIM signing without moving to a managed email API, or you're already sending via SMTP/mailgun-style transports where the provider doesn't sign with your domain.
• You need per-tenant or per-custom-domain DKIM keys — a single provider-level key won't satisfy the requirement.
• You're on, or planning, a Laravel major upgrade and want dependencies that track new framework releases promptly (v3.6.0 is a maintenance release proving that).
• Your team is small and you want the smallest possible surface area: this is a focused package, not a full mail-deliverability suite.

Look elsewhere when:

• You already send through SES/Postmark/SendGrid with Easy DKIM configured — you'd be duplicating signing and adding key-management burden for no deliverability gain.
• You need DMARC reporting/aggregation, BIMI, SPF management, or reputation monitoring — this package signs; it does not measure or manage deliverability.
• You require vendor SLAs, support contracts, or a compliance attestation — this is a community-maintained package with a single primary maintainer. That's a bus-factor consideration for anything customer-facing at scale.
• You need inbound email parsing or advanced templating — out of scope.

How to Pitch It (Stakeholders)

To executives: We can sign our outgoing email with our own DKIM keys inside the existing Laravel app instead of buying or expanding an email vendor contract. That keeps per-customer sending domains (a recurring ask from larger accounts) in our control and avoids a procurement cycle. Cost is engineering time plus key-management hygiene, not a new subscription.

To engineering: It's a small, single-purpose package — DKIM signing for Laravel's mailer. v3.6.0 is a compatibility-only release adding Laravel 13.x support, with no API changes, no deprecations, and no migration work; upgrading from v3.5.0 is a routine dependency bump. Adopt it if we want signing keys we own; skip it if our ESP already signs on our behalf. Note it's effectively single-maintainer, so if we depend on it for production mail we should pin versions, keep a fallback to provider-side signing, and treat key rotation as an owned runbook item rather than a library concern.
