Email Deliverability Tips for Free Plans
Free email marketing tools often have lower deliverability rates than paid plans. Here's how to maximize deliverability:
1. Authenticate your domain: Set up SPF, DKIM, and DMARC records. Most free tools provide instructions for this. Without authentication, emails may land in spam.
2. Use double opt-in: Requires subscribers to confirm their email address. Reduces fake signups and improves list quality. Brevo, ConvertKit, and MailerLite support double opt-in on free plans.
3. Warm up your list: Don't send 9,000 emails on day one with Brevo. Start with small batches (100-200) and gradually increase volume over 2-4 weeks.
4. Clean your list regularly: Remove bounced, unsubscribed, and inactive emails. Most free tools show bounce rates — keep yours under 2%.
5. Avoid spam trigger words: Words like "FREE," "GUARANTEE," "ACT NOW," and excessive capitalization trigger spam filters. Use natural, conversational language.
6. Include unsubscribe link: All free tools include automatic unsubscribe links. Never remove them — it's legally required (CAN-SPAM, GDPR).
7. Test before sending: Send a test email to yourself before sending to your full list. Check how it looks on mobile and desktop.
1. Not reading the fine print: Free plans have limits. Know them before committing. Mailchimp's 500-contact limit can be reached quickly.
2. Using a free email domain: Sending from gmail.com or outlook.com looks unprofessional. Use a custom domain email (yourname@yourbusiness.com) for better deliverability and trust.
3. Not segmenting the list: Even on free plans, use basic segmentation (tags in ConvertKit, groups in Mailchimp) to send targeted emails rather than blasting everyone.
4. Ignoring analytics: Free plans include basic analytics. Check open rates (aim for 20%+), click rates (aim for 2%+), and unsubscribe rates (keep under 0.5%).
5. Buying email lists: Never buy email lists. It's against all free tools' terms of service, damages deliverability, and can get your account suspended.
6. Not having a welcome email: Set up an automatic welcome email for new subscribers. ConvertKit and MailerLite include this on free plans. A welcome email sets expectations and improves engagement.
7. Over-sending on Brevo: Brevo's 300 emails/day limit means you can't send to 5,000 contacts in one day. Plan your sends over multiple days or upgrade to a paid plan.
Free plans work for small lists and basic campaigns. You'll outgrow them when:
1. You need advanced automation: Multi-step workflows, conditional logic, behavior-triggered emails — these require paid plans on all tools.
2. You need A/B testing: No free email marketing tool includes A/B testing. You need at least Mailchimp Essentials ($13/mo) or MailerLite Growing Business ($10/mo).
3. You need custom branding: All free plans include the tool's logo in your emails. Removing it requires a paid plan.
4. You need advanced segmentation: Free plans offer basic segmentation. For demographic, behavioral, or predictive segmentation, you need paid plans.
5. You exceed contact limits: Mailchimp (500), ConvertKit (1,000), MailerLite (1,000), HubSpot (1,000). Only Brevo has unlimited contacts.
6. You need dedicated IP: A dedicated IP improves deliverability for high-volume senders. No free plan includes this.
7. You need priority support: Free plans offer community support or limited email support. For priority support, you need a paid plan.
Tips for Maximizing Free Email Marketing
- Choose Brevo for large lists: Unlimited contacts means no pressure to upgrade as list grows
- Choose MailerLite for most emails: 12,000 emails/month is the highest free limit
- Use ConvertKit for automation: Only free tool with visual automation builder
- Combine with free tools: Use Canva (free) for email design, Google Analytics (free) for tracking
- Clean your list regularly: Remove inactive subscribers to stay within contact limits
- Use double opt-in: Reduces fake signups and keeps your list quality high
- Start free, upgrade selectively: Only upgrade when you hit a specific limitation
