Summary
Welcome emails are crucial for onboarding new customers, yet many businesses struggle with them landing in spam or junk folders. This often stems from underlying deliverability issues that impact your overall sender reputation, affecting not just welcome sequences but other campaigns too. Understanding the root causes, from poor list acquisition practices to technical misconfigurations, is the first step toward ensuring your initial interactions land squarely in the inbox.
Key findings
- Reputation is key: Mailbox providers, like Gmail, don't differentiate between a welcome email and a promotional email; they assess your domain and IP reputation as a whole. A poor reputation affects all your sends, including crucial welcome messages.
- User engagement matters: The way recipients interact with your welcome emails (opening, clicking, moving from junk) heavily influences future inbox placement. Negative actions, such as marking as spam, are strong signals.
- Acquisition quality: How you collect email addresses directly impacts your list quality and, consequently, your deliverability. Using opt-in methods that encourage valid and engaged subscribers is vital.
- Technical setup: Proper email authentication (SPF, DKIM, DMARC) is foundational. Missing or misconfigured records can cause emails to fail authentication checks and land in spam, even for legitimate sends.
Key considerations
- Monitor your reputation: Regularly check your domain and IP reputation using tools like Google Postmaster Tools, especially if you send to Gmail users. This provides insights into your spam rate, IP reputation, and domain reputation.
- Implement authentication: Ensure your SPF, DKIM, and DMARC records are correctly set up and aligned. This validates your sending identity and builds trust with mailbox providers. Learn more in our simple guide to DMARC, SPF, and DKIM.
- Review subscriber source: Examine how new subscribers are added to your list. Pop-ups and forms should clearly set expectations and encourage real, engaged sign-ups to avoid fake addresses or disengaged users that lead to spam complaints.
- Analyze engagement metrics: Track your open rates, click-through rates, unsubscribe rates, and spam complaint rates over time. A sudden drop in engagement or spike in complaints, even on welcome emails, can signal a deliverability problem. Our guide on how to diagnose email deliverability issues can provide further assistance.
What email marketers say
Email marketers often find it perplexing when their welcome emails, designed for positive first impressions, land in the spam folder. This issue highlights that even the most anticipated messages are subject to the same deliverability rules and reputation checks as bulk campaigns. The consensus among marketers points to list quality, sender reputation, and recipient engagement as primary factors, rather than the content type itself.
Key opinions
- Reputation impacts all emails: Many marketers acknowledge that mailbox providers do not distinguish between welcome emails and other types of messages when assessing sender reputation. If your overall brand reputation is compromised, all emails suffer.
- List acquisition is critical: The methods used to acquire new subscribers, such as pop-up forms, can influence the quality of the list and whether subscribers are genuinely interested, affecting initial engagement and ultimately deliverability.
- User action is a strong signal: How recipients interact with the very first email they receive from you (or don't interact, by ignoring or marking as spam) heavily influences future inbox placement for that user and your domain generally.
- Sudden changes indicate issues: If emails suddenly start going to spam, marketers often look for recent changes in sending volume, content, or list management practices.
Key considerations
- Evaluate subscriber journey: Assess the entire customer journey, from signup to the first email. Ensure that the initial email fulfills the customer's expectation set at the point of subscription.
- Educate subscribers: Encourage new subscribers to check their junk or promotions folder and move your welcome email to their primary inbox. This positive action sends a strong signal to mailbox providers.
- Monitor engagement trends: Beyond just complaints, track opens, clicks, and unsubscribes. Low engagement, even if spam rates are low, can degrade your reputation over time and cause issues. You can also monitor your email deliverability rate.
- Segment and warm up: If you're a new sender or have a new IP/domain, proper warming up of your sending infrastructure is crucial. Also, segmenting your list can help target the most engaged subscribers first. Mailgun recommends several tips to avoid emails going to spam, including focusing on list hygiene and relevant content.
Marketer view
Marketer from Email Geeks explains that if welcome emails are going to spam, the primary concern is a deliverability issue, meaning the mailbox provider has flagged the email as undesirable. They suggest analyzing how new subscribers are acquired and if the emails sent align with the customer's initial expectations upon signup.
Marketer view
Marketer from Email Geeks suggests that marketers need to investigate if the spam issue is isolated to a single ISP or if it is a widespread problem across multiple mailbox providers. They note that messages land in spam when the domain or IP reputation is low, which can be due to high spam complaints or poor subscriber engagement.
What the experts say
Email deliverability experts concur that welcome emails going to spam is a symptom of broader reputation issues, not typically a problem inherent to the welcome email itself. They emphasize a holistic view of sender reputation, influenced by user engagement, technical compliance, and even the reputation of the sending website. The initial interaction with a new subscriber is paramount, as negative signals from this first touchpoint can severely damage deliverability for all subsequent emails.
Key opinions
- Overall sender reputation: Experts stress that welcome emails are subject to the same filtering mechanisms as any other email. If your domain or IP reputation is poor, all emails, including welcome sequences, will suffer.
- Recipient engagement feedback: The actions (or inactions) of recipients upon receiving the first email are crucial signals for mailbox providers. If subscribers don't open, or worse, mark as spam, it negatively impacts future deliverability.
- Website reputation link: Some experts point out that Google's assessment of your website's reputation can also influence email deliverability, suggesting a broader connection between overall online presence and inbox placement.
- Spam trap hits: Sending to spam traps, often a result of poor list hygiene or purchased lists, can instantly blacklist (or blocklist) your sending reputation, affecting even welcome emails. Learn more about spam traps and how they work.
Key considerations
- Focus on permission: Ensure that your subscriber acquisition methods prioritize explicit permission and managing expectations. This helps ensure genuine engagement and reduces the likelihood of spam complaints.
- Incentivize positive action: Design your signup process and welcome email to encourage recipients to engage, such as adding your address to their contacts or moving the email from spam to the inbox.
- Proactive monitoring: Continuously monitor your deliverability across various mailbox providers, not just for welcome emails, but for all sending. Use data from Google Postmaster Tools and other reputation services. For more on this, see our guide on understanding your email domain reputation.
- Content and infrastructure: While engagement is key, technical factors like proper email authentication and avoiding spammy content are foundational. Ensure your email content is clean and doesn't trigger filters. Twilio offers tips on keeping emails out of spam, including consistent sending volume and clean lists.
Expert view
Deliverability expert from SpamResource.com notes that reputation is often the core issue when emails go to spam. They explain that a bad sender reputation means mailbox providers will be highly suspicious of all mail, including the first welcome message, leading to automatic junk placement.
Expert view
Deliverability expert from WordtotheWise.com advises that a key reason welcome emails are blocked is due to a lack of proper authentication, which fails to prove the sender's legitimacy. They emphasize that DMARC, SPF, and DKIM are fundamental to building trust with receiving servers.
What the documentation says
Official documentation from major mailbox providers and email service platforms consistently highlights the importance of sender reputation, email authentication, and user engagement as critical factors for inbox placement. While welcome emails are often highly anticipated, they are not immune to filtering if foundational deliverability best practices are not followed. These guidelines underscore the necessity of strong technical compliance and adherence to user-centric sending policies to ensure messages reach their intended recipients.
Key findings
- Sender reputation is paramount: Mailbox providers primarily filter emails based on the sender's reputation, which includes factors like IP address, domain, and historical sending behavior. A poor reputation means even welcome emails can be rejected or junked.
- Authentication is mandatory: Proper implementation of SPF, DKIM, and DMARC is essential for proving the authenticity of your emails and preventing spoofing. Without these, emails are highly likely to land in spam.
- User engagement metrics: Positive user engagement (opens, clicks, replies) and low complaint rates are crucial signals that your emails are wanted. Mailbox providers use these signals to inform filtering decisions.
- Content relevance and unsubscribe: Content that appears suspicious or lacking a clear unsubscribe option can trigger spam filters. Even welcome emails should be clear, concise, and offer an easy opt-out.
Key considerations
- Adhere to sending limits: New senders, or those with new IPs, should start with low volumes and gradually increase, a process known as IP warming. Exceeding recommended volumes too quickly can lead to throttling or blocklisting.
- Monitor blocklists: Regularly check if your sending IPs or domains are on any public or private blocklists (or blacklists). Being listed means your emails, including welcome messages, will likely be rejected. See our in-depth guide to email blocklists.
- Implement DMARC policy: Beyond just having DMARC, progress to a p=quarantine or p=reject policy to enforce authentication and protect your domain's reputation. Our guide on safely transitioning your DMARC policy can help.
- Regular list hygiene: Regularly remove inactive or invalid email addresses from your list to maintain high engagement and avoid hitting spam traps, which could derail your welcome emails and other campaigns.
Technical article
Google Postmaster Tools documentation states that domain and IP reputation scores directly influence deliverability to Gmail users. It explains that a poor reputation, influenced by spam rates and user feedback, will cause emails, regardless of their content (like welcome messages), to land in spam.
Technical article
Mailchimp's documentation on avoiding spam filters emphasizes that including an unsubscribe link is crucial for compliance and deliverability. They also point out that too many attachments or a lack of proper email authentication (SPF, DKIM) can cause emails to be flagged as spam.
