# One-time campaigns or triggered sends?

## One-time campaigns

A common approach to sending direct mail is to send a single, large campaign to a target audience. 

**At Lob,** **a "one-time" campaign is a one-to-many method of mail distribution to a broad audience using a single set of mailing instructions.** 

{% hint style="success" %}
Popular use cases for one-time campaigns include sending acquisition or cross-sell mailers, retail promotions, annual policy updates, end-of-life notices for a sunsetting product, referral campaigns, etc. 
{% endhint %}

Traditionally, sending a campaign meant negotiating RFPs for every project, long lead times with lots of back-and-forth with the printer, imperfect audience lists, and use of generic creatives that lacked personalization, if any. 

With Lob, you can create campaigns using our flexible settings and guidance, choose from various delivery options, and apply dynamic personalization at unprecedented granular levels. 

One-time campaign execution is easy in the Lob Dashboard via [Campaigns](/print-and-mail/send-mail/launch-your-first-campaign.md), or programmatically via our [Campaigns API](/print-and-mail/send-mail/send-campaigns-via-the-campaigns-api.md).

  * Target Delivery, cards or buckslips have different campaign send minimums&#x20;
* Some campaign-specific settings may override your account-level settings, such as merge variable strictness or cancellation windows

## Automated campaigns (trigger-based)

Another common way to send direct mail is to individually dispatch mail, usually initiated by pre-programmed logic or event within an orchestration workflow.&#x20;

**"Triggered" mail is an automated process that sends mail to a single recipient when they meet a pre-set condition or take a defined set of actions within a certain timeline.**&#x20;

Lob refers to these event- or trigger-based campaigns as automated campaigns. &#x20;

{% hint style="success" %}
Popular triggered use cases include post-signup onboarding mail, abandoned cart recovery, order notices or monthly statements, product retargeting, and follow-up confirmations. &#x20;
{% endhint %}

Using Lob's single endpoint APIs, you can create a custom trigger automation from scratch, or take advantage of popular pre-built [API integrations](/print-and-mail/integrations/api-integrations.md) to connect to a platform you already use for your digital channels. Or for a less technical lift, you can automate your sends [directly from the Lob dashboard](/print-and-mail/integrations/no-code-integrations.md).
