Custom Email Content
Custom Email Content
Summary
Custom Email Content ensures your warmup emails reflect your business's real communication style, industry, and tone.
Goal: Simulate realistic communication behaviour to help build an authentic mailbox reputation.
Warmup emails:
- Are generated in English
- Rotate automatically once a day
- Include natural variation to mimic human behaviour
How It Works
During Set-Up
When adding a new sending address (via wizard or manual setup), you will complete the Custom Email Content wizard.
You'll answer structured questions about:
- Business type Industry
- Communication tone
- Typical email context
Based on your responses, the system generates warmup templates aligned with your real communication style.
Once saved, the configuration becomes active immediately.
After Setup (Self-Managed Accounts)
- Content configuration can be updated once per day
- During the cooldown period, warmup emails continue generating from the last saved configuration
Content Behaviour & System Logic
Automatic Rotation
Content refreshes every daily to:
- Reduce repetition
- Introduce variation
- Simulate natural communication patterns
This structured variation helps prevent behavioural uniformity.
Language Standard
All content is generated in English to maintain:
- Consistent quality standards
- Controlled linguistic structure
- Reliable behavioural modelling across providers
Human-Level Variation
Real people don't send perfectly identical emails.
To simulate authentic behaviour, the system may include:
- Natural phrasing differences
- Formatting variation
- Occasional minor typos
These variations:
- Do not harm reputation
- Do not affect deliverability
- Can reinforce authenticity signals
Mailbox providers expect human inconsistency - not robotic perfection.
Why does content matter for warmup?
Mailbox providers analyse behavioural patterns; not just volume and engagement.
Highly repetitive, identical content across accounts can:
- Look artificial
- Create detectable behavioural patterns
- Reduce realism in engagement modelling
By introducing structured variation and business-aligned messaging, Warmup simulates:
- Real conversational flow
- Context-aware phrasing
- Natural formatting
- Human-like imperfection
This helps your mailbox build a reputation profile that mirrors real-world usage.
How this helps your business
1. Realistic behavioural simulation
Your warmup emails reflect how your business actually communicates.
A B2B SaaS company shouldn't sound like a lifestyle blog.
An ecommerce brand shouldn't sound like a law firm.
Custom Email Content aligns warmup behaviour with your real industry and tone.
2. Natural content variation
Content rotates automatically, reducing repetition and creating more realistic sending patterns.
3. Consistent quality
All content is generated in English to maintain consistent standards and behavioural reliability.
4. Human-like realism
Real communication includes small imperfections.
Warmup intentionally introduces subtle variation and occasional minor typos to mirror authentic human behaviour.
Frequently Asked Questions
How often does the content refresh?
Content refreshes daily from when you make changes.
What language is the generated content in?
All content is generated in English to maintain consistent quality, structure, and reliable behavioural modelling.
I noticed a typo in my generated content. Why?
This is intentional. The system simulates real human behaviour, including minor imperfections. Small typos do not harm reputation or deliverability and can reinforce authenticity signals.
Does Custom Email Content improve deliverability?
It supports deliverability indirectly by strengthening behavioural realism. Overall deliverability still depends on factors like infrastructure, volume control, engagement behaviour, DNS setup, and sending patterns.
Can I disable this feature?
No. You will be asked to complete the Custom Email Content wizard when you set up your sending account. You won't have to amend this again unless you'd like to change the content generated to something different than the original instructions.
