Struggling with Email Deliverability: How to Monetize 100k Emails?

I have a list of 100k emails from women 50+ in the USA.

I'm looking for ways to monetize this through email campaigns, advertising, or other strategies.

The challenge is that lately most emails land directly in the spam folder if you use a new domain or address, even when sending with Amazon SES or other providers with good IP reputation.

On top of that, Gmail filters have become even stricter, pushing most marketing emails into the Promotions tab, which people rarely check.

Any advice or proven methods to get better deliverability and actually reach the inbox?

For a list that size and niche, deliverability is the key challenge.

1. Warm up gradually: Start by sending small batches from a verified domain and gradually increase volume.
2. Segment & personalize: Target based on age range, interests, or past activity to boost engagement.
3. Use verified sending tools: Consider services like Klaviyo, Active Campaign, or Postmark they handle authentication (SPF, DKIM, DMARC) and reputation management.

Avoid blasting the full list at once; engagement signals are what keep emails in the inbox.

Set up standard SPF DNS Verify sending server is allowed to send, Use "clean" domain and email.
