For freelancers and consultants, there is no phrase more frustrating than: “Sorry, I never saw the invoice.” You sent it on the 1st. It is now the 15th. You have been waiting for payment, silently fuming, while the client honestly didn’t know they owed you money because your WordPress invoicing plugin (like Sprout Invoices, Sliced Invoices, or WooCommerce) failed to deliver the email. In this scenario, a technical glitch becomes a financial crisis. Your rent is due, but your money is stuck in digital limbo. WP Email Log is the tool that eliminates this excuse. It provides the Proof of Delivery you need to chase payments confidently. Instead of asking meekly “Did you get my invoice?”, you can say “I see the invoice was sent on Tuesday at 9 AM; shall I resend it to a different address?” In this review, we will explore how this plugin acts as a critical accounts receivable tool.
The “Lost Invoice” Diagnosis
Many freelancers use WordPress plugins to generate professional invoices. These rely on wp_mail to send the PDF to the client. If your server IP is slightly graylisted, that invoice hits the client’s Spam folder. WP Email Log lets you diagnose this instantly.
-
The Check: Before you send an awkward follow-up email, check the log.
-
The Confirmation: If the log shows “Sent,” you know the issue is on the client’s end (Spam filter or organizational firewall).
-
The Action: You can email the client personally: “Hi, our system sent the invoice yesterday. It might be in your Spam folder. Here is a direct link.” This proactive approach shortens the payment cycle significantly.
The “One-Click” Reminder (Resend)
Clients lose emails. They open the invoice on their phone, forget about it, and then can’t find it later. Asking you to “send it again” usually requires logging into your invoicing plugin, navigating to the specific record, and finding the “Send Reminder” button (if it exists). WP Email Log speeds this up.
-
The Feature: Search “Invoice” in the log. Click Resend.
-
The Power Move: If the client says “My accountant needs a copy,” you can edit the recipient field in the Resend modal and fire a copy directly to their finance department. You remove the friction that delays your check.
Verifying Automated Dunning
If you sell retainers or recurring services, your system sends automated reminders: “Your card is about to expire” or “Payment Overdue.” If these emails fail, the client’s service gets cut off. They get angry. You lose revenue. The SaaS Monitor ensures your automated collector is actually working.
-
The Alert: If your email infrastructure goes down the day your invoices are scheduled to go out, the Monitor alerts you. You can pause the billing or switch SMTP providers, ensuring you don’t face a month of failed collections.
The “Paper Trail” for Disputes
Sometimes, a client will claim they didn’t receive the invoice to avoid late fees. “You can’t charge me a late fee if you never sent the bill!” WP Email Log is your evidence locker.
-
Forensic Proof: You have a timestamped record of the exact email generation.
-
Body Preview: You can show that the email contained the correct amount and due date.
-
The Leverage: This data allows you to enforce your contract terms firmly but fairly. You can prove you did your job, so they must do theirs (pay you).
Auto-Forwarding to Your Accountant
You need to keep track of your sent invoices, too. The Auto-Forward feature allows you to pipe every outgoing invoice email to your own accounting inbox (e.g., receipts@mybusiness.com).
-
The Benefit: This ensures you have a copy of every bill sent to every client, stored safely off-site. When tax season comes, you don’t have to dig through WordPress; you have everything in your own email folders.
Pricing vs. One Late Check
-
Personal License: $59/year. If this plugin helps you collect one $500 invoice a week earlier than usual, the improved liquidity covers the cost instantly.
Final Verdict
You did the work. You deserve to get paid. Don’t let a flaky PHP mail function stand between you and your money. WP Email Log gives freelancers the visibility and tools to ensure that invoices land in inboxes, not void spaces. It turns the passive act of “billing” into an active, managed process that protects your cash flow.
