Multi-step sequences with built-in optimization
Build email sequences with wait periods, A/B variants per step, conditional logic, and spintax. Smart optimization auto-pauses underperforming variants. Every campaign runs on your own dedicated IPs with sticky hash assignment per mailbox.

Sequences that run themselves
IF/THEN/ELSE branches based on any variable. Different leads see different copy depending on their data.
When your email copy gets stale, SendKit detects it and can auto-regenerate or pause the variant.
Fire webhooks for lead.created, lead.replied, email.sent, email.opened, and lead.bounced events on each campaign.
Auto-stop on reply, stop on auto-reply, or stop when anyone at the same company replies. Plus CC/BCC and unsubscribe link options.
From draft to sending in minutes
Add email steps with wait periods in days or hours. Create A/B variants (A, B, C, and more) per step, add conditional IF/THEN/ELSE logic per variable, and use spintax like {option1|option2|option3} with nested support.
Pick which mailboxes to send from. SendKit handles sender rotation (round-robin, random, or priority) and detects each lead's timezone from their country or city if imported.
Set your sending schedule with start/end times, working days, and holiday skipping. Smart optimization automatically pauses underperforming A/B variants. Replies stop the sequence for that lead instantly.
Run campaigns for multiple clients on dedicated IPs. Each mailbox permanently maps to the same IP via MD5 hash. No shared infrastructure, no shared reputation risk.
Rotate sends across dozens of mailboxes with round-robin, random, or priority modes. Set sending windows per campaign so nobody blows past daily limits.
Use {{firstName}}, {{company}}, and custom field variables. Add conditional logic per step so different leads see different copy based on their data.
Sequences built on your own IPs
Your campaigns run on dedicated IPs. Not shared ones.
Most cold email tools put everyone on shared sending servers. When another user gets flagged, your deliverability drops too. SendKit gives every account dedicated IPs with sticky hash assignment. Each mailbox permanently maps to the same IP. Your sender reputation belongs to you.
Timezone-aware sending with granular controls
SendKit detects each lead's timezone from their country or city data. Set per-campaign sending windows with start and end times, choose working days, and skip holidays. Emails arrive during your prospect's business hours, not yours.
Smart optimization picks your best variant
Don't babysit your A/B tests. Smart optimization automatically shifts volume toward winning variants and pauses underperformers. Configure minimum sends per variant, minimum days before optimization kicks in, and auto-pause thresholds.
Got questions? We've got answers.
There's no fixed limit. Add as many email steps with wait periods (days or hours) as your campaign needs. Most high-performing sequences use 4 to 7 steps.
