Good that you’re thinking about this early — email can work really well, but only if the foundation is right.
A few basics I’d definitely focus on first:
make sure your domain is properly set up (SPF, DKIM, DMARC), warm up your inbox before sending volume, and don’t rush into big lists. A small, clean, relevant list will always outperform a large generic one.
Also, try to avoid thinking in terms of “blasts.” Even for something like an email checking tool, positioning and targeting matter a lot. For example, you could tailor messaging differently for agencies, SaaS founders, or sales teams — especially in niches like lead gen for SaaS or marketing agencies where deliverability is a real pain point.
I’ve seen teams like Salesar handle this well — they put a lot of emphasis on deliverability, clean data, and aligning messaging with the audience, rather than just sending more emails. Their approach is more about building a repeatable system and focusing on quality conversations instead of volume.
So I’d say:
get the technical setup right
keep your data clean and targeted
and treat email as a conversation, not a broadcast
That usually makes a big difference early on.
