Subscription emails for users who haven't paid you yet

Your first day with Adapty Mail

Your questions, answered

• How much revenue should my subscription app make from email?

  Based on 5 billion emails sent through subscription apps, median apps make 4.3% of total revenue from email. Top apps reach 13.2%. The gap isn’t audience size — most subscription apps already have the users. It’s tooling. Most apps haven’t set up a lifecycle email engine because traditional platforms like Braze require 3-6 months to configure, a dedicated copywriter, and custom dev work for revenue attribution. Adapty Mail removes those three blockers.

• How long does it take to set up lifecycle email for a subscription app?

  Traditional email platforms like Braze, Customer.io, or Iterable typically take 3-6 months to configure for a subscription app. The time goes into domain authentication, audience segmentation, custom events for in-app purchase tracking, and writing initial sequences. AI-based tools built specifically for subscription apps (like Adapty Mail) can compress this to a single afternoon by auto-generating sequences from your App Store listing and handling deliverability setup automatically.

• Do you need a copywriter to run lifecycle email for a mobile app?

  Traditionally yes — a marketing copywriter typically writes 7-15 emails per lifecycle sequence (onboarding, trial conversion, win-back, renewal). Modern AI email tools can generate subscription-app-specific copy by reading your App Store listing and using it as a brand voice reference. The AI writes the initial sequences; a reviewer approves or edits them before sending. This removes the copywriter as a blocker for small teams without dedicated marketing headcount.

• How do subscription apps attribute email revenue to specific in-app purchases?

  Standard email platforms report opens, clicks, and web conversions but can’t close the loop on mobile in-app purchases because iOS StoreKit and Google Play Billing process transactions outside the browser. Subscription-specific email tools solve this by tying each email’s checkout link to the user’s unique profile ID (for example, Adapty’s profile_id) and recording when that ID later makes a purchase. This lets you see revenue per email and per sequence, not just open rates.

• What are DKIM, SPF, and DMARC, and do I need them for email marketing?

  Yes, you need all three for any serious email marketing. DKIM, SPF, and DMARC are email authentication standards that prove your emails actually come from your domain (not a spammer spoofing it). Without them, your emails land in spam folders. Most modern email platforms — including Adapty Mail — configure these automatically when you connect a sending domain, but the DNS records need to be added to your domain registrar to verify ownership.

• What's the difference between general ESPs and email tools built for subscription apps?

  General ESPs (Braze, Customer.io, Iterable, Mailchimp) are built for web businesses and multi-channel marketing. Tools built specifically for subscription apps (like Adapty Mail) differ in three ways: (1) setup is faster because subscription-specific integrations for iOS/Android purchases are prebuilt, (2) revenue attribution ties directly to in-app purchases instead of requiring custom event tracking, and (3) pricing is usually outcome-based rather than per-seat or per-contact.

• Can AI write subscription app emails that convert?

  AI-generated email copy has improved significantly because models can now read product context — App Store screenshots, value props, brand tone — and write in a specific voice. For subscription apps, AI works best when it has access to product-specific inputs (the app’s listing, its paywall copy, its positioning) rather than generic prompts. The pattern that works: AI generates the full sequence, a human reviews and edits, A/B testing determines winners. Fully autonomous AI email (no human review) is not recommended for emails going to paying users.

• How should subscription apps price email marketing tools?

  Three common pricing models: (1) per-contact monthly fees (Mailchimp, Customer.io) — predictable but expensive at scale, (2) platform fees plus per-seat costs (Braze, Iterable) — enterprise-focused, typically $50K+/year minimums, (3) percentage of incremental revenue driven (Adapty Mail — 20%) — outcome-aligned, zero cost if no revenue. The right model depends on how predictable your email revenue is and how much you want to pre-commit.

• Do subscription apps need a separate ESP if they use a mobile-specific email tool?

  Usually not, for lifecycle email. Mobile-specific tools like Adapty Mail handle the full subscription lifecycle (onboarding, trial conversion, win-back, renewal) including sending infrastructure. However, some apps keep a separate ESP for transactional emails (password resets, receipts) or broadcast campaigns to non-subscribers. The decision is usually based on whether your email program extends beyond the subscription lifecycle.

• What email metrics matter most for subscription apps?

  Revenue per email, revenue per sequence, and trial-to-paid conversion rate — not open rate or CTR. Opens and clicks are vanity metrics that have become unreliable since Apple Mail Privacy Protection (which auto-opens most iOS emails). Subscription apps should measure email success by the revenue each email or sequence drives, attributable via in-app purchase tracking. Benchmark: top subscription apps generate 9-13% of total revenue from email, median apps generate 4.3%.
