How to Send an Email Campaign

Email Campaigns are one-time, broadcast-style emails you can use to send newsletters, updates, announcements, or any other type of marketing content to your audience. Campaigns are great for sale/special offer, date, or event-specific content.

If you want to send content based on a Contact's behavior and preferences, check out our guide to Automations!

🚦 Before Getting Started

Create a Sender Profile and a List, Segment, or created before you begin building your Campaign

In This Guide

Create a New Campaign

To create a new Campaign:

  1. Click the Campaign icon
  2. Click New Campaign 
  3. Click Create Email Campaign

Campaign Settings

Name your Campaign, select a Sender Profile, set your Audience, and configure advanced settings on the left hand pane of the Settings & Content page.

Campaign Name

Enter a descriptive name for your Campaign under Campaign Name. This name will identify the Campaign on the Campaigns page, it is not the subject line for your Campaign email.

Sender Profile

Select an existing or create a new Sender Profile to send the Campaign from.


Select Lists, Segments, or Tags from the the Send to (will receive the Campaign) or Don't send to (will NOT receive the Campaign) dropdown menus.

Use the audience size estimate button to calculate an estimate of how many Contacts are included in the Audience options selected:

🚨 Don't send to overrides Send to

If a Contact is on a List Segment, or Tag in the Send to section but is also on a List, Segment, or Tag in the Don't send to section, they will not receive the Campaign. Contacts in the Don't send to section are not included in the Audience count.

UTM Tracking

Check the Customize UTM checkbox to edit UTM tracking information for the Campaign. If you have global UTM tracking set up, you will see your global settings when the button is checked. Change or add new UTM parameters and values for this Campaign only.

RSS Feed

Check the RSS Feed box if you'd like to add your Campaign to an existing RSS feed on your website, then enter your RSS feed's URL.


Check the Experiments box if you'd like to turn on Campaign Experiments for your Campaign.

Campaign Content

Set your subject and preheader, and access the email builder for your Campaign on the right hand pane of the Settings & Content page.

Subject & Preheader

Subject The subject line should be an attention-getter. Use 4-6 compelling words for best results, and consider using the personalization icon to add personalized data from your Contacts' profiles, like their first name.
Preheader The preheader text is used build curiosity and increase your open rates by displaying a summary of your message in your audience's inbox!


Click Create Email to go to the Email builder, where you can either use a template for your Campaign or design it from scratch! Read the guide to Sendlane's email builder for details about everything you can achieve with our MJML drag-and-drop email builder.

Sendlane has many resources to help clarify a winning marketing strategy for your brand! Check out our blog 6 Email Design Tips to Increase Engagement for tips on creating a style guide for your brand, optimizing for mobile devices, personalization, color psychology, and call-to-action best practices.

In addition to design resources, consult content resources that focus on how content can affect deliverability, such as Why is my email going to the spam folder?

Here are a few simple rules that can help your email reach as many Contacts as possible:

  • Emails should be 40% images at most. Some inbox providers block automatic image downloading which means Contacts who use those services will not immediately see any images in your email. Images are also not readable by screen readers. Use text or buttons whenever possible!
  • Content order matters. Contacts see the top of your email first; if the first sections don't grab them, they likely won't continue scrolling. Keep logo images and generic brand information at the top of an email as small as possible while still being readable, or consider moving it to the bottom of the email.
  • Use one call-to-action per email. When emails have multiple calls-to-action, Contacts aren't sure which is the most important. Keep your content focused and concise so Contacts can easily scan it!

Campaign Statuses

The Campaigns page's Status column provides a Status for all Campaigns

  • Completed - The Campaign has finished sending. We suggest waiting 24 hours before reviewing the Campaign's report to give your Contacts enough time to engage with your Campaign.
  • Denied - The campaign has been reviewed and denied by the Sendlane Compliance Team. Common reasons for denial include spam-like or misleading content; broken, unmasked, or untrusted URLs, and poor image-to-text ratio (i.e. single, large image with hardly any text).
  • Experimenting - The Campaign was sent and has Campaign Experiments turned on.
  • Draft - The Campaign has not been sent.
  • Pending Compliance Review - The Sendlane Compliance Team is reviewing the Campaign. Most campaigns are approved within 24 hours. If after 24 hours your campaign has not been approved, please reach out to our Support Team.
  • Scheduled - The Campaign is scheduled to be sent at a specified date and time.
  • Sending - The Campaign is being sent. The Campaign may remain in this status for a period of time if the audience is large, or if the Campaign is being sent via Machine Learning Open Predictability.  
  • Stopped - The Campaign was manually stopped after sending began.

My Contacts are seeing blank emails! 

The Campaign likely used one image as the entire email. Contacts may be seeing the image because they have not downloaded or allowed images in their inbox settings, or they are receiving the plain text-only format of an email that has no text inside. Best practices suggest a ratio of 60% text and 40% images.
