# Quick Implementation

> What's the easiest way to integrate with thanks.io?

For most customers, the easiest integration is to add recipients to a thanks.io mailing list and let the customer manage automation inside thanks.io.

## Choose the Simplest Path

Use this rule of thumb:

* If your application needs to trigger one-off mailers directly, use the [Quickstart](/quickstart).
* If your users should control campaign timing, creatives, and automation in thanks.io, use the [campaign workflow](/workflows/campaign).

## When Automation Is Easier

The automation path is usually easier because thanks.io handles:

* campaign timing
* creative management
* billing
* recurring workflow logic

Your integration only needs to add the right recipients to the right mailing list.

## When Direct API Sends Are Easier

Use direct API sends when your application needs to:

* create a mail order immediately from in-app activity
* control the recipient, creative, and message payload directly
* send one-off mailers without routing users into thanks.io campaign setup

## Recommended Next Step

If you are unsure, start with the [campaign workflow](/workflows/campaign). If you already know you need direct sends from your app, go to the [Quickstart](/quickstart).
