Deliverability best practices

Pidgely handles the infrastructure side of deliverability. The rest depends on what you send and to whom. This page lists both, with links to longer articles on the Pidgely blog.

#What Pidgely does for you

• Authentication: DKIM (RSA-2048) per domain and an SPF-aligned return path, so DMARC passes on both. See Domains & DNS.
• Separate streams: transactional and broadcast mail use separate IP pools. See Transactional vs marketing streams.
• IP warm-up and pacing: new IPs ramp up gradually, concurrency is capped per destination, and each account sends at its own pace. See How to warm up a new sending IP.
• Bounce and complaint processing: VERP return paths, DSN parsing and feedback loops feed the suppression list automatically. See VERP and automated bounce handling and Feedback loops.
• One-click unsubscribe (RFC 8058) on every broadcast. See One-click unsubscribe.
• Reputation guard: sending pauses automatically above 4% bounces or 0.1% complaints, before the damage spreads (details).

#Checklist for your side

1. Publish DMARC on your domain. Start with p=none and a reporting address, then tighten. Gmail and Yahoo require it for bulk senders: the checklist.
2. Send only to people who asked. Use double opt-in for newsletters; never buy lists.
3. Keep complaints under 0.1%. Make unsubscribing easy: include {{{PIDGELY_UNSUBSCRIBE_URL}}} visibly in every broadcast.
4. Separate transactional and marketing mail. Use broadcasts (or "stream": "broadcast") for marketing; consider a subdomain such as news.acme.com for it.
5. Use a consistent From address with a real name and a monitored reply_to.
6. Send both HTML and text (Pidgely generates text from HTML if you don't), keep HTML light, and avoid link shorteners.
7. Remove inactive recipients from marketing segments after a few months of silence.
8. Watch webhooks: track email.bounced, email.complained and email.delivery_delayed per campaign.
9. Ramp up new volume gradually instead of sending your whole list on day one.
