Smartlead
Sales & OutreachTestedAsk how your cold email is really doing in plain language: reply rates, deliverability, inbox health, and which campaigns are working.
OVERVIEW
Smartlead is a cold email and outbound platform used by sales teams and lead-gen agencies to run sequenced campaigns across many sending mailboxes, warm inboxes, and track replies. Agentcy connects to your Smartlead account with a read-only API key (BYOK) so you can ask plain-language questions about campaign performance, deliverability, and lead status without clicking through the Smartlead dashboard, right inside Claude, ChatGPT, or your preferred AI client.
This integration is read-only by design. Agentcy never sends email, creates or pauses campaigns, or changes leads. Ask an account-wide question like "how is my outbound doing this month" and Agentcy pulls each campaign's analytics and reads back one synthesized answer (reply rate, best campaign, bounce trend) instead of a wall of raw rows. It can go deep too: per-sequence-step performance, per-lead reply categories, inbox-warmup health by mailbox, and the full message thread for any prospect.
Pairs especially well with GA4 and your CRM to close the loop on outbound: of the prospects Smartlead emailed, which replied, which hit your site, and which entered the pipeline.

TIPS
4Read-only by policy. Agentcy never sends email, creates or pauses campaigns, or changes leads. Use Smartlead directly for any sending or campaign changes.
API access requires a paid Smartlead plan. Rate limits scale with your plan tier, so very heavy querying on a lower tier can return a rate-limit response. Agentcy caches results for 5 minutes to smooth this out.
Daily and per-sequence breakdowns are capped at a 30-day window per request. Ask about a specific period and the brain picks the right window.
There is no single account-wide stats endpoint in Smartlead. For account-wide questions Agentcy lists your campaigns and reads each one's analytics, then synthesizes the combined answer — which is exactly the kind of multi-step work the agent handles for you.
