what is email deliverability and why does it matter for cold outreach

Email deliverability is whether your outbound emails actually reach the inbox instead of spam. For cold outreach, it determines how many of your 1,000+ monthly prospects ever see your message. Poor deliverability kills reply rates, burns domain reputation, and collapses your booked-meetings pipeline before a sequence even runs. OnyxSend monitors sender health, rotates sending infrastructure, and warms domains automatically so your multi-channel sequences land in the inbox and convert prospects into qualified meetings.
