If you’re sending emails from a new email address or domain - especially through a marketing platform - it’s completely normal to experience lower deliverability at first.
That’s because email providers (like Gmail, Outlook, and Yahoo) don’t know you yet. They need to see that:
You’re a legitimate sender, not a spammer
People actually want your emails, and
Your messages are safe and relevant
In short: when you send mass emails from a new address without warming it up, inbox providers can assume it’s spam.
That’s why warming up your new email address and encouraging engagement from your contacts is so important.
Let’s walk through how to do it right 
Think of your new email address like a fresh start - it needs time to build trust.
Here’s how to warm it up:
Start small. Send to your most engaged contacts first (friends, loyal clients, or coworkers).
Send 20–50 emails per day for the first few days and increase slowly each week.
Mix in personal messages - not just marketing blasts - to show genuine activity.
Continue increasing your sending volume over 2–4 weeks before launching large campaigns.
Why it matters: A gradual warm-up shows email providers you’re a consistent, trustworthy sender, not a spam bot.
Email engagement is everything for deliverability.
The more people open, click, reply, and interact with your emails, the more email providers believe your messages belong in the inbox.
Here are some practical engagement boosters:
Ask Contacts to Add You to Their Address BookEncourage your subscribers to add your email address to their contacts (or “safe senders”) list.
When they do, it sends a powerful signal to email providers that you’re trusted.
You can say something like:
“To make sure you don’t miss future updates, please add hello@inbox.yourdomain.com to your contacts!”
Ask Them to Reply to YouReplies are gold for deliverability. They tell email providers that a real conversation is happening.
Include a line in your welcome or first email like:
“Hit reply and let me know what kind of tips you’d love to see next!”
Even a few replies make a big difference in building your sender reputation.
Include Click-Worthy LinksClicks show engagement too.
Create emails that naturally encourage clicks:
“Click here to grab your free checklist.”
“See this week’s top tips.”
“Tap to book your next appointment.”
Keep your links clean (no shortened URL companies like bit.ly) and make sure they point to secure pages (https://…).
Ask Them to Email You FirstThis is a powerful but often-overlooked trick:
Ask your audience to send you an email first - even before you start sending campaigns from your new address.
For example:
“Hey there! I just switched to a new email address — could you send me a quick message at hello@inbox.yourdomain.com to say hi? That’ll help make sure my messages don’t land in spam.”
When they initiate contact, it tells email providers there’s genuine two-way communication between you and your audience.
Email filters look for certain red flags - both in wording and design.
Avoid:
Using all caps or too many exclamation points (FREE!!! BUY NOW!!!)
Embedding too many images without text
Linking to shady or shortened URLs (like bit.ly)
Overusing promotional language (“guaranteed income,” “act fast,” etc.)
Do:
Keep a natural, conversational tone
Personalize your messages with names or past interactions
Balance text and visuals
Use clear, relevant subject lines
Think of your email like a friendly message from you — not a billboard.
Step 4: Keep Your List Clean and Engaged
Deliverability is heavily influenced by how people interact with your emails.
Regularly:
Remove bounced or invalid emails
Segment your lists (don’t send every email to everyone)
Re-engage inactive subscribers or remove them after a few months
Encourage subscribers to reply, open, and click your emails
Clean lists = higher deliverability.
Step 5: Make It Fun - Offer a Giveaway or Challenge!
Want your contacts to actually do all those engagement actions?
Make it fun with a mini giveaway or challenge!
Here’s how:
Announce a small giveaway (like a gift card, beauty product, or business tool).
Ask people to:
Add your new email address to their contacts 
Reply to your email 
Click one of the links 
Or send you a message from their inbox 
Let them know each action counts as an “entry” to your giveaway!
This not only helps your deliverability but also builds excitement and early engagement with your new address.
Consistency builds trust with inbox providers and your subscribers.
Don’t disappear for weeks and then send a big blast - that’s a red flag.
Instead:
Send on a predictable schedule (weekly or biweekly is great)
Keep your tone and style consistent
Always deliver value your audience looks forward to
Warming up your email address isn’t just a technical task - it’s about building trust with both your audience and email platforms.
When you:
Start slow
Authenticate your domain
Encourage clicks, replies, and saves
And make it fun with a giveaway
…you’ll quickly earn your spot in the inbox.
Your new email address will be seen as a trusted, reputable sender - and that means higher open rates, more engagement, and better results for every campaign you send.
