title: What Email Providers Are Best for Cold Emailing
description: Compare email providers and choose the best one for cold outreach.
Overview
The effectiveness of email providers for cold emailing depends on factors like your target audience, setup and configuration, and sending practices and limits. No provider is perfect on its own; success depends on how well you follow best practices.
Below is a comparison of major providers to help you choose the right one for your needs.
Recommended Email Providers
Provider | Daily Sending Limit | Pros | Cons | Best For |
|---|---|---|---|---|
Google Workspace (G Suite) | 30–50 emails per day per sender (recommended) | High deliverability and sender trust; excellent inbox placement; familiar interface; strong spam filtering | Higher cost per mailbox; strict sending limits; accounts can be suspended for poor practices | Small to mid-size teams prioritizing deliverability and brand reputation |
Microsoft 365 / Outlook | 30–50 emails per day per sender (recommended) | Trusted by enterprise recipients; strong email management; good deliverability to Outlook inboxes | Can be complex to configure; Outlook spam filters are aggressive | B2B outreach targeting corporate Outlook users |
Zoho Mail | ~500 emails per day per account on standard plans | Affordable pricing; easy setup; good for smaller campaigns | Lower sending limits; less established reputation than Google or Microsoft | Startups and small businesses with tight budgets |
AWS SES | Up to 14 emails per second (~1.2M/day) once out of sandbox; sandbox default is 200/day | Extremely cost-effective at scale; full control over sending infrastructure; high volume capability | Requires technical setup (DNS, DKIM, SPF); no native inbox or UI; support is limited | Developers and high-volume senders with technical resources |
SendGrid | Up to 600 emails/day on free tier; paid plans scale to millions | Reliable SMTP infrastructure; good analytics and event webhooks; easy API integration | Shared IP reputation on lower tiers; can still hit spam folders if not warmed up properly | High-volume campaigns and application-driven transactional email |
Important: Regardless of the provider you choose, SalesBlink recommends sending 30–50 emails per day per email sender. Provider limits may be higher, but exceeding this range hurts deliverability. Always focus on proper warm-up, sending limits, list quality, and personalization.
