Frequently asked questions

What should a small business set up first?

Capture, welcome, receipts, and review asks — in that order. Those four touch revenue directly; everything else (win-back sophistication, scoring, SMS programs) waits until customers flow. One weekend on a free tier covers all four.

Resist audience-building infrastructure before customer traction exists; regulars fund everything else.

How much should small businesses spend on email?

Near zero initially (free tiers genuinely cover early needs), then scale cost with revenue — never with contacts alone. Per-contact pricing punishes exactly the community growth small businesses need; pay-per-send survives it. Revisit math at each doubling; vendors reprice and needs change.

Review generation typically pays for the entire stack within a quarter; install it before debating paid tiers.

Can owners really run email themselves?

Yes, with AI-generated sequences and billing-native triggers doing heavy lifting — owners report about an hour a month steady state. Keys: generated skeletons over blank canvases, four core journeys maximum, exits and suppression automated instead of list-managed, documentation the next helper inherits.

Systems scale; mysteries require the owner's memory forever.

When should small businesses add SMS?

For time-sensitive utility — appointment reminders, order-ready notices, event changes — with explicit consent and sparing promotional use. SMS cuts no-shows dramatically but costs per message and annoys fast; reserve promotional texts for proven buyers with clear value. Email carries depth, SMS carries moments.

Model per-message economics before adding steps; SMS bills differently than email.

How do you get reviews without begging?

Through timing plus ease: asks within 24 hours of successful transactions with one-tap links, staff mentioning reviews conversationally, and single follow-ups for non-responders. Detractors route to private feedback first — sequencing service recovery before review asks is legitimate operations, not manipulation.

Measure reviews per hundred transactions; steady cadence beats sporadic pushes.

What breaks when small businesses grow email?

Contact-tier pricing, list-wide blasts replacing relevance, shared service-and-marketing reputations, and tribal-knowledge automations nobody dares touch. Each breaks at predictable multiples — review quarterly against doubling-forward math and evolve on schedule rather than under crisis.

Scheduled evolution beats emergency migration every time.
