Here’s what to expect from us
Tone
Transparent, calm, confident
Why I Chose This
People don’t like surprises in their inbox unless they’re good ones. This subject line builds trust. It shows you value communication and consent. I like using this in B2B environments or anytime you’re about to send a lot of onboarding content.
When to Use
Perfect when you’re about to kick off a nurture sequence, drip campaign, or a trial that involves a series of emails. Especially for SaaS or products with frequent updates.
Tips
- Spell out the frequency. Tell people how often they’ll hear from you.
- Be upfront about value. Don’t hide key info in fine print. Be clear from the start.
This subject line can also be:
- Let’s walk you through the next steps
- What happens next with [Company Name]
- What you’ll get from us
Welcome to [Product]. Your trial starts now
Tone
Clear, informative, professional
Why I Chose This
This is one of the most direct welcome subject lines used in a SaaS environment. The goal isn’t emotion here. It’s clarity. People need to know two things fast: they’re in, and their trial has started. If your onboarding is time-sensitive, say a 7-day or 14-day window, then this phrasing matters more than ever.
When to Use
Use it for product trials, early access programs, or freemium tools with a limited window. This line sets expectations without needing a second read.
Tips
- Include end date. Spell out when the trial ends. Add a countdown if possible.
- Offer setup help inside. A good subject opens the door, but setup guides keep users walking through it.
This subject line can also be:
- Your free trial just started
- Welcome to [Product]. Explore before your trial ends
Subject: Welcome to Heroic Inbox. Your trial starts now

First things first: confirm your preferences
Tone
Clear, respectful, calm
Why I Chose This
Regulations like GDPR encourage transparent data choices, so leading with “preferences” shows respect. A decisive opening also filters contacts who never intended to engage, protecting deliverability long-term.
When to Use
Perfect for newsletters, fintech apps, or any platform handling sensitive notifications. Place it before marketing drips begin.
Tips
- Keep the CTA single. One click should open a preference center.
- Remind of value. Tell users what they gain by tuning messages instead of unsubscribing.
Welcome kit inside: open for shortcuts
Tone
Practical, clear, confident
Why I Chose This
To rise above average open rate, I front-load tangible valu: “kit”, and promise efficiency: “shortcuts.” Readers know exactly what waits beyond the click, which builds trust.
When to Use
Perfect for complex tools, developer platforms, or B2B services where a cheatsheet or keyboard-shortcut card speeds adoption.
Tips
- Bundle assets (PDF guide, video, quick actions) so the “kit” feels real.
- Add expiry to the shortcuts link if you want urgency without hype.
Your time means a lot. Thanks for choosing us
Tone:
Grateful, humble, and confident.
Why I Chose This Subject Line:
This subject line respects the reader’s time while reinforcing their choice.
I’ve seen it used in onboarding emails, and it tends to get strong engagement. People like to feel seen, and this line delivers that feeling.
When to Use:
Use this after a user signs up, attends a webinar, or makes a purchase.
The goal is to say, “We noticed you, and we’re thankful,” without sounding scripted or transactional.
Tips:
- Use this subject line as part of a thank-you series that includes a follow-up with helpful resources or tips.
- Pair with a clean email body. One image, one message. Don’t overdesign.
- Add a personal signature if possible. It feels less corporate that way.
