TL;DR

Scaling cold email from 100 to 1,000+ emails/day requires switching from Google Workspace or Outlook to bulk SMTP accounts. Google Workspace costs $6+/user/month with a 2,000 email/day limit and suspension risk; Winnr provides 50 SMTP accounts for $69/mo ($1.38/mailbox) with automatic SPF, DKIM, and DMARC. Import accounts via CSV into a sales automation tool like Smartlead, then warm, ramp, and send.

Introduction

Cold email outreach remains a pre-eminent strategy for acquiring leads even though it gets a lot of flak. Most businesses are actively generating essential leads from cold outreach but they might not be happy with the results.

If you are tired of sending cold email from your Gmail or Outlook account and not seeing enough leads as a result, you can often solve this by the power of scale. Instead of sending 100 emails per day, send 1,000. If you do it right, it can change the whole game.

Background

Typically an outbound sales team will send a lot of cold email through their corporate email accounts. Often they are using some sales automation software like Apollo to do this in semi-bulk. For example, they are often plugging in their Google Workspace accounts and automating emails. But there are huge downsides to using your Google Workspace accounts for cold outreach.

Problems with using Google Workspace or Outlook accounts for cold outreach

Some common challenges include:

  1. Sending Limits: Traditional email platforms impose daily sending limits, restricting the number of emails you can send in a given time frame. These hard limits mean you have to pay for many accounts to scale up, which leads to problem #2
  2. Cost Considerations: Setting up multiple accounts on platforms like Google and Outlook can be costly, particularly for startups operating on tight budgets. To set up 50 accounts, you will often pay well over $1,000/month
  3. Risk of Suspension: Google and Outlook will often suspend your accounts without notice and this can halt your outbound sales efforts in their tracks. If this is your main day-to-day email, it can prevent you from essential communication with important customers
  4. Time Suck: It takes hours to configure new accounts, add DKIM/SPF/DMARC authentication for any new domains, and then manage these accounts. They are not meant to be managed in bulk

Generate email accounts in bulk

Winnr is a cold email infrastructure platform that provides bulk SMTP accounts with the same deliverability as Google Workspace -- without the cost, sending limits, or suspension risk. Winnr's Startup plan includes 50 fully authenticated email accounts for $69/mo ($1.38/mailbox), compared to $300+/mo for the same number of Google Workspace accounts. Every account comes with 100% passing SPF, DKIM, and DMARC configured automatically.

You can generate 50 email accounts in just a few hours with Winnr. You will get a CSV with all your accounts, ready to import into your sending tool.

How to use these bulk email accounts to start sending

Sales automation tools like smartlead.ai are specifically designed to handle large volumes of emails efficiently using a large number of email accounts supplied by winnr. You can take your CSV of accounts from winnr and easily import it into smartlead.ai. It will look something like this:

Importing into Smartlead

Export your winnr accounts as a CSV, then import directly into Smartlead.ai under Settings → Email Accounts → Bulk Import. All SMTP credentials, IMAP details, and display names are pre-filled.

You can then automatically warm leads, automate email campaigns, track replies, and monitor deliverability. Here is what an automated email campaign looks like in smartlead.ai

Automated campaign flow

Set up a multi-step sequence: Day 1 → initial email, Day 4 → follow-up with new angle, Day 8 → breakup email. Smartlead rotates across all your winnr accounts automatically to distribute sending volume.

Winnr provides 50 SMTP accounts for $69/mo or 200 accounts for $189/mo -- all with automatic SPF, DKIM, and DMARC authentication, a full REST API for programmatic management, and a 90% deliverability guarantee. Pair Winnr accounts with a sales automation tool like Smartlead, and you can scale from 100 to 1,000+ emails per day without the cost or suspension risk of traditional email providers.
