1. Permission First: Who Are You Allowed to Email?
Sending commercial electronic messages in Turkey is governed by the Law on the Regulation of Electronic Commerce and its regulations. The general rule is prior consent from the recipient; for messages to sole traders and merchants prior consent is not required, but the recipient must be able to opt out in every message. Record-keeping for consent and opt-outs, obligations under the national Message Management System (İYS) and the exceptions depend on your situation, so get a definitive legal assessment from a specialist. Here we only cover the technical and practical side.
2. Keep Your List Clean
Old, long-unused or bulk-purchased lists cause two problems: sending to addresses that no longer exist (bounces) and complaints from people who do not know you. Both damage your sender reputation. Remove bounced addresses, never re-add people who unsubscribed, and note where and when each contact came from.
3. Do Not Raise Volume Suddenly
Mail providers treat unusually rising volume as suspicious. An account that sends a few messages a day and suddenly sends hundreds can see its messages land in spam. Spreading sends over several days, staying within the provider's daily limit and growing volume gradually protects your sender reputation.
4. Do Not Write to the Same Person Too Often
Frequency is a quiet driver of deliverability. Writing to the same person repeatedly in short intervals raises complaint and unsubscribe rates. A per-person sending frequency limit protects both the recipient and your list.
5. Verify Your Domain's Identity
If you send from a corporate domain, correctly configured SPF, DKIM and DMARC records prove to the recipient's server that the message really comes from you. Without them, even excellent content looks suspicious. They are set up once and then do their work quietly.
6. Make Leaving Easy
Hiding the unsubscribe link seems to protect list size in the short term but comes back as complaints in the long term. One-click unsubscribe, permanent blocklisting of those who leave and sender details in every message are part of both compliance and trust.
How We Carry These Rules into the Product
These six rules were our starting point when designing UlakPost: sending is spread across a queue according to the daily limit, a frequency limit applies to repeat sends to the same person, every message carries a one-click unsubscribe and people who leave are permanently blocklisted. The contact card also stores consent status, source and date. Messages are sent from your own Gmail or Outlook account, and your contact list stays on your computer.
