Spam is not “email I do not like.” It is mail people did not reasonably agree to. Build with clear opt-in language and an unsubscribe that works—your future deliverability depends on it.
Consent and expectations
State what you send and how often on the signup form. Pre-checked boxes and hidden disclosures create complaints that hurt everyone on your IP pool.
Rules vary by country. If you have EU subscribers, read current guidance on lawful bases and record-keeping—not blog summaries from 2019.
Lead magnets that match search or social intent
A checklist that solves one painful step outperforms a generic “eBook” nobody opens. Name the outcome in the title: “Cold email subject lines for SaaS founders (10 tested).”
Welcome sequence: deliver promise, then rhythm
Email 1: instant delivery + what to expect. Emails 2–3: teach something small and verifiable. Then move to your normal cadence—weekly beats daily unless you truly have that much signal.
Deliverability: authentication and hygiene
Set up SPF, DKIM, DMARC with your ESP’s docs. Remove chronic non-openers after long idle periods if your ESP recommends it; focus on engaged segments for launches.
What to track
- Reply rate and clicks to sales pages.
- Spam complaint rate (keep tiny).
- List growth vs churn monthly.
A small engaged list beats a bloated cold warehouse.
Metrics that matter
Optimize for revenue per subscriber and content feedback, not open-rate games that change with Apple MPP and inbox quirks.
