Direct Mail (by e3 Software) is a Mac desktop email marketing application popular with designers, photographers, and small businesses who prefer local Mac-native workflows over cloud SaaS. The unsubscribe mechanism uses the [unsubscribe] merge field in the message template, replaced at send time with a signed URL scoped to the recipient list entry. Direct Mail routes sends through the e3 Software cloud sending infrastructure which handles RFC 8058 headers automatically for authenticated sending domains. Suppression is stored locally in the Direct Mail Mac app database with cloud sync to the e3 Software account.

How to add the unsubscribe tag in directmailmac.com
Place the merge tag exactly as shown below in the email template. directmailmac.com replaces it at send time with a signed URL scoped to the recipient and campaign.
[unsubscribe]For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="[unsubscribe]">Unsubscribe from this list</a>Manual placement in message template, auto-embedded in default templates
Yes, automatic via e3 Software cloud sending infrastructure The recipient's mailbox provider (Gmail, Yahoo) uses the List-Unsubscribe-Post header to expose the native one-click button on the message. Requires domain authentication with DKIM and DMARC.
Direct Mail syncs suppression across multiple Mac installations only when signed into the same e3 Software account. Standalone Mac installations without account sync store opt-outs only in the local database, creating suppression drift for team environments. Sign in with the same e3 Software account across all team Mac installations to prevent this.

[unsubscribe]. Direct Mail replaces it at send time with a signed URL scoped to the recipient list entry. - Wrap it in an anchor:
<a href="[unsubscribe]">Unsubscribe</a>. - Configure the e3 Software account under Direct Mail > Preferences > Sending account for cloud sync and RFC 8058 header injection.

Local database and cloud sync
Direct Mail syncs suppression across multiple Mac installations only when signed into the same e3 Software account. Standalone Mac installations without account sync store opt-outs only in the local database, creating suppression drift for team environments. Sign in with the same e3 Software account across all team Mac installations to prevent this. Single-user setups (photographer, designer, solo entrepreneur) do not have this issue since the local database is the authoritative source of truth.
RFC 8058 via e3 Software cloud infrastructure
Direct Mail routes sends through the e3 Software cloud sending infrastructure which handles RFC 8058 List-Unsubscribe and List-Unsubscribe-Post header injection automatically for authenticated sending domains. The Mac desktop app itself does not inject headers; the cloud relay does. SPF and DKIM records must be verified for the sending domain. Small business senders using Direct Mail with the e3 Software account get one-click compliance without additional configuration.
Design-oriented workflow for photographers and creators
Direct Mail attracts photographers, designers, and creative professionals who value Mac-native design tools and visual template editors. The suppression and RFC 8058 compliance model is designed to be invisible to non-technical users: sign into the e3 Software account, verify the sending domain, and compliance is handled automatically. This lower cognitive load compared to configuring cloud SaaS ESPs makes Direct Mail popular in the Mac creative professional segment.
Frequently Asked Questions
What is the Direct Mail unsubscribe tag?
The merge field is [unsubscribe]. Direct Mail replaces it at send time with a signed URL scoped to the recipient list entry. Use it inside an anchor: <a href="[unsubscribe]">Unsubscribe</a>.
Where is Direct Mail suppression data stored?
In the local Mac database with cloud sync to the e3 Software account when signed in. Multi-installation team environments need account sync enabled to prevent suppression drift; single-user setups do not have this issue.
Does Direct Mail support one-click unsubscribe for Gmail and Yahoo?
Yes via the e3 Software cloud sending infrastructure. Direct Mail routes sends through the cloud relay which injects List-Unsubscribe and List-Unsubscribe-Post headers on authenticated domains. Sign in with an e3 Software account and verify the sending domain.
Is Direct Mail suitable for team collaboration?
Yes with account sync enabled. Teams should sign into the same e3 Software account on all Mac installations to sync suppression, contact lists, and templates. Standalone installations without sync create drift and duplicated work.
Can I migrate a Direct Mail suppression list to a SaaS ESP?
Yes. Export the suppression list from Direct Mail as CSV, then import into the destination ESP suppression / blocklist. This preserves opt-out history during migration and prevents accidentally re-emailing unsubscribed contacts.
