When you'll need this
Read this article if you want to understand all available paid add-ons, you're trying to decide which add-ons are worth the investment, or you need to understand pricing before budgeting for SendX.
Inbox Testing
Inbox Testing lets you check where your emails land before you send a campaign. It tests your email against multiple inbox providers to see if you're hitting the inbox or spam folder.
Pricing
Package | Price |
10 inbox placement tests | $25 |
Each test checks your email across multiple inbox providers (Gmail, Outlook, Yahoo, etc.) and reports where it landed.
When to use it
Before launching a major campaign
After making significant changes to your email templates
When you notice deliverability issues
When testing a new sending domain or IP
How it works
Purchase a test pack from the Add-ons section
Create your email campaign as usual
Run an inbox test before sending
Review the report showing inbox vs. spam placement
Make adjustments if needed, then send
Inbox Warmup
Inbox Warmup automatically improves your sender reputation by simulating engagement with your emails. The system opens your emails and moves any that land in spam back to the inbox.
Pricing
Daily Volume | Monthly Price |
2,000 emails/day | $200/month |
5,000 emails/day | $300/month |
10,000 emails/day | $400/month |
Over 10,000/day | Contact sales |
When to use it

When recovering from deliverability issues
When you've been dormant and are resuming sending
As ongoing reputation maintenance for high-volume senders
Important notes
This is an automated background service
It supplements, not replaces, good sending practices
Results take 2-4 weeks to show improvement
Works best combined with quality list hygiene
Live Warmup (with Seeds)
Live Warmup is a more hands-on approach than automated Inbox Warmup. SendX sends emails to internally owned inboxes that manually engage with your emails, clicking links and marking as important.
Pricing

When to use it

Common questions
Can I try an add-on before committing?
Most add-ons don't have free trials. Inbox Testing is pay-per-use, so you can buy a small pack to test. For warmup services, you'll need to commit to at least one month.
Can I cancel an add-on anytime?
Yes, but cancellation takes effect at the end of your current billing cycle. No partial refunds.
Do add-on prices ever change?
Prices may be updated periodically. Your current subscription rate is locked in until you cancel and re-subscribe.
What if I need something not listed here?
Contact SendX support. For enterprise needs, custom packages may be available.
Are there bundle discounts?
Not currently. Each add-on is priced and billed separately.
