A/B Test Campaigns
What it does: Tests different subject line and preview text combinations on a portion of your audience, then automatically sends the winning version to everyone else.
When to use it: When you want data to decide which subject line will perform best rather than guessing. Particularly valuable for important campaigns where maximizing opens matters.

Configurable wait time before sending winner

Access: Campaigns > A/B Split Test > Create A/B Split Test
Drip Campaigns
What it does: Sends a sequence of emails automatically over time to contacts who enter the campaign.
When to use it: When you want to nurture contacts through a series of emails without manually sending each one. The sequence runs automatically for each contact based on when they enter.
Key features:
Multiple emails in a sequence with configurable delays between each
Delays in minutes, hours, or days
Contacts enter via lists, tags, or segments
Each contact progresses through the sequence independently
Execution tracking shows which email each contact has received
Full reporting per email in the sequence
Can pause, edit, and resume
How it works:
You create a series of emails with delays between them
You define entry conditions (which contacts should enter) through automation rules
When a contact meets the conditions, they start at email 1
They receive each subsequent email after the specified delays
Example use cases:
Welcome series for new subscribers
Onboarding sequence for new customers
Educational email course
Lead nurturing over several weeks
Access: Campaigns > Drip > Create Drip
RSS Email Campaigns
What it does: Automatically sends emails when your RSS feed has new content, on a schedule you define.
When to use it: When you want to notify subscribers about new blog posts, articles, podcast episodes, or other content that publishes to an RSS feed. Once set up, it runs on autopilot.
Key features:
Monitors your RSS feed for new posts
Sends on your schedule: daily, weekly, or monthly
Only sends when new content exists (no empty emails)
Dynamic content tags pull post titles, descriptions, dates, and links
Option to include all new posts or just the latest one
Drag and Drop editor only
Can exclude specific days (for daily sends)
How it works:
You provide your RSS feed URL
You design an email template with dynamic post tags
You set a schedule (daily at 9am, weekly on Monday, etc.)
SendX checks your feed at each scheduled time
If there's new content, it sends; if not, it skips that send
Example use cases:
Blog digest newsletter
Podcast episode announcements
News roundup emails
Product update feeds
Access: Campaigns > RSS > Create RSS
Auto Trigger Campaigns
What it does: Sends a single email to individual contacts when they trigger an automation rule.
When to use it: When you want a simple "when X happens, send this email" setup without building a full workflow. It's the easiest way to send triggered emails.
Key features:
Create email content separately from automation logic
Connect to any automation trigger (list subscription, tag added, form submission, integration events)
Optional delay before sending (minutes, hours, or days)
One campaign can be used by multiple automations
Drag and Drop, Plain Text, and SendX AI editors available
Campaign must be active for automations to send it
How it works:
You create and save the Auto Trigger campaign content
You create an automation rule with your trigger condition
You add "Send Auto Trigger Campaign" as the action
When a contact meets the trigger, they get the email
Example use cases:
Welcome email when someone joins a list
Thank you email after form submission
Follow-up after a purchase (via integration)
Re-engagement email when a tag is added
Access: Campaigns > Auto Trigger > Create Auto Trigger
Workflow Emails
What it does: Sends emails as part of complex, multi-path automations with conditions, branching, and multiple actions.
When to use it: When you need sophisticated automation logic, such as sending different emails based on contact behavior, or orchestrating a sequence with conditions and decision points.
Key features:
Visual workflow builder with drag-and-drop nodes
Multiple entry triggers and conditions
Branching paths based on contact attributes or behavior
Delays, waits, and timing controls
Multiple emails in different branches
Actions beyond email: add tags, update fields, move to lists
Goal tracking to measure conversions
How it works:
You build a workflow with entry conditions
You add email nodes, delays, conditions, and branches
You connect the flow visually
Contacts enter and move through the workflow based on their actions and your conditions
Example use cases:
Abandoned cart sequence with multiple follow-ups
Lead scoring and routing based on engagement
Onboarding that adapts based on user actions
Re-engagement campaigns with escalating offers
Complex nurture sequences with conditional content
Access: Automate > Workflows > Create Workflow
Choosing the Right Campaign Type
"I want to send a one-time email to my list"
Use Newsletter. It's straightforward: pick your audience, schedule your send, done.
"I want to test which subject line works better"
Use A/B Test. You'll get data-driven results rather than guessing.
"I want new subscribers to receive a series of emails automatically"
Use Drip Campaign. Set up your sequence once, and every new subscriber goes through it.
"I want subscribers notified when I publish new blog posts"
Use RSS Campaign. It monitors your feed and handles everything automatically.
"I want to send an email when someone fills out a form"
Use Auto Trigger. Create the email, set up a simple automation, and you're done.
"I want different emails sent based on whether someone clicked a link"
Use Workflow. You need branching logic, which requires the visual workflow builder.
"I'm not sure which to use"
Start with the simplest option that meets your needs:
Newsletter for one-time sends
Auto Trigger for simple triggered emails
Drip for basic email sequences
Workflow for anything complex
You can always migrate to a more sophisticated option later if your needs grow.
