Customer Communication Automation: Email, SMS, and Policy Controls

Start here

Overview

Automated customer communications accelerate response but create regulatory and brand risk if unmanaged. This guide defines template libraries, approval tiers, and channel policies.

Core concept

Definition

Policy-controlled automation separates message intent (appointment reminder, payment due) from content variants—each variant reviewed and versioned.

Business impact

Why it matters

TCPA, CAN-SPAM, industry-specific rules, and brand trust require controls—not ad hoc sends from individual tools.

Practical model

Framework

Template registry

Name, audience, channel, legal footer, and expiration for periodic review.

Draft vs send

AI drafts within approved slots; sensitive categories require human send.

Implementation detail

Detailed breakdown

Suppression and preference centers

Centralize opt-outs; sync back to CRM immediately.

In practice

Real-world example

A financial services team gated promotional SMS behind compliance-approved templates while allowing AI to personalize within fixed bounds.

Avoid these

Common mistakes

Multiple tools sending without unified preference data.
Letting models invent claims outside approved language.

Engineering layer

Technical patterns

Policy as data

`{ max_per_day, quiet_hours_tz, channels_allowed, consent_required }` per segment.
Pre-send hook queries policy store; blocks emit audit reason code.

Build patterns

Code examples

Quiet hours gate

Converts recipient TZ; defers job if inside window.

TypeScript

export function canSendNow(recipientTz, quiet) {
  const local = new Date().toLocaleString('en-US', { timeZone: recipientTz });
  const hour = new Date(local).getHours();
  return hour < quiet.start || hour >= quiet.end;
}

System architecture

YAML

[Campaign / workflow trigger]
        → [Recipient resolution + consent DB]
        → [Policy engine: caps + quiet hours]
        → [Provider adapter: Twilio / SendGrid]
        → [Delivery webhooks → status table]
