# Adjusting sending frequency and expected completion time

You may choose from 4 sending frequencies with different velocities for sending messages.  

{% hint style="danger" %}
Remember that too high of a frequency may lead to unexpected bans. We suggest starters should always start with "Safe" frequency first.

<details>

<summary><strong>The expected completion time is calculated based on the total number of recipients and the sending frequency.</strong></summary>

Let's say the total number of recipients is 100, and the sending frequency is 30 seconds per message, the expected completion time will be 50 mins.

Depending on your campaign, it is up to you what sending frequency option works best for your campaign. Once you have made up your mind, you may head to [Scheduling a campaign](/features/campaign/creating-a-campaign/scheduling-a-campaign.md).
